The Subagent page becomes the Tasks page per the approved Variant-D design:
- tasks-model.ts feeds BOTH modes from one pre-order node list: graph
canvas (TasksGraph: layered nodes over bezier edges, drag-pan,
wheel-zoom-to-cursor, phase frames, bottom-right control cluster) and
the classic tree (TasksTree: keyboard navigable) — the view toggle and
fold toggle stay reachable in both modes.
- Workflow runs (workflows.list) hang under their origin agent; member
agents re-parent under the run node, missing ones synthesize from run
data; completed leaf agents fold into per-parent aggregate nodes
(click or cluster toggle to expand/re-collapse).
- Agent Teams (experimental): roster enriches nodes; a header chip opens
the shared task board popover with basic CAS operations (complete /
reopen / delete / reassign / create / edit); no experimental layer →
the whole block hides (structural degradation).
- Background jobs move into a bottom drawer that auto-collapses at 8+
agents (manual toggle wins); job output opens as an anchored popover
(event replay, never the model's cursor); two-click kill preserved.
- Live activity lines render as glyph + tool + args (tool-icons map onto
host primitive icons).
- Node click jumps to the transcript; ⓘ opens the detail popover;
popovers follow the selection-popup dismissal contract (Escape /
outside click / anchor off-screen via IntersectionObserver).
- tasksViewMode pref (graph default) with a select row in settings;
58 new copy keys across zh/en/ja + 18 third-language dictionaries;
dead CSS from the old tree/dock pruned.
- Tests: 6 new page-interaction specs (auto-collapse, both-mode toggle,
jump, fold, popover); jobs-view suite re-pointed at the popover;
prefs/builtins/smoke lock tests updated for the new pref.
DSH 0.1.7-alpha.1 is 1299 commits past 0.1.6-alpha.2 and rewrites four
contracts this plugin was built on. The peer floor moves to
^0.1.7-alpha.1 (semver's prerelease rule means ^0.1.6-alpha.2 can never
match a 0.1.7 prerelease); 0.1.6-alpha.2 and earlier stay on v0.19.1.
Released as 0.21.0-alpha.1 (dist-tag alpha).
Hard breaks:
- dsh-settings was rewritten: register(ns, schema) is gone, a form is
addressed by the plugin row's Loader entry id and read from the
module's exported Config. The preferences are merged into Config and
marked volatile — which requires DSH's own schemastery, because only
that build wraps a volatile field in the cosmokit reference the
loader's volatile commit walks. With the public package a settings
write reports success and revision 1 while the effective value never
changes.
- ui-primitives renamed its whole icon family (IconXxx14/16 ->
IconXxxRegular/Medium): 26 imported symbols, 17 files. The failing
mode is render-time, not load-time. Five call sites that relied on the
old 14px default now pass size={14} explicitly.
- Session format v4 rejects source.kind === 'plugin'; the side-chat
boundary injection now writes plugin:dsh-better-sidebar, the same kind
DSH's own v3->v4 migration produces, so historical threads survive.
Tool results moved to role 'tool' with top-level content/isError; all
four parsers accept both shapes.
- The client session snapshot dropped subagentsByParent/jobsBySession
and the on-demand subagent-catalog observation API. The Tasks page
reads projectionsBySession and a new jobs.list route.
Yields and convergence:
- The read-only previews go to DSH's documentpreview (Office->PDF, a
spreadsheet worker, zoom, per-directory refresh); editor.canOpen
refuses those 26 extensions. Markdown, HTML (with its sandbox
switches) and the editable code buffer stay.
- The host browser kind is desktop-profile-only now, so the web e2e
lanes expect no browser entry and assert its absence.
- Link takeover claims only urlTarget links and passes the rest to the
host, fixing a regression from the 0.1.6 round: the fallback pointed
at a 'browser' type the plugin no longer registers, so http links in
its own markdown did nothing.
Also fixed, found along the way:
- The file tree refreshes live (new directory watch over the plugin's
own socket), since the plugin owns the `files` kind.
- ctx.sessions.list has no `current` field at either tag; the three
readers were dead. They now use ctx.sidebarRight.mounted.
- package.json.files was missing lib/client-locale.js.
- Two genuinely dead call sites: sessions.openSubagent/open/
refreshSubagents do not exist on the current baseline, so the
topology click, the jump-back and the retry were all no-ops.
- The test harness window shim lacked addEventListener, which the 0.1.7
primitives call at module-evaluation time; and the e2e token exchange
needs Playwright's request stack, not Node's fetch.
DSH 0.1.6-alpha.2 ships a right-Sidebar terminal and a right-Sidebar browser
of its own. Both were things this plugin had built from scratch, so keeping
them meant two implementations of one surface plus a plugin that shadows a
host type the product is actively developing.
Terminal: the plugin's whole PTY stack goes — the UI-tab manager, the
agent-owned registry, the lazy node-pty loader, the eight model-facing
terminal_* tools, the xterm view and its font/link/scrollback helpers, and
the cross-session 'pinned terminal' rail that existed only to keep a terminal
alive across a session switch. The host's terminal kind becomes the only
provider, which also retires the node-pty dependency, its pnpm allowBuilds
entry, and the installer's -Repair mode (issue #140's whole class of
'node-pty failed to load' support).
Model-facing capability note: the plugin used to inject terminal_* tools
(off by default). Those are the model's only cross-call persistent terminal,
and DSH's own equivalent (@deepseek-ai/dsh-tool-terminal) is not mounted by
any shipped bundle, so removing them leaves the model with the one-shot
bash/pwsh tools only. That is the accepted cost of not maintaining a second
PTY surface; the README documents how to enable the upstream toolset.
Browser: the plugin's browser tab type is dropped, so the host's own browser
kind owns embedded pages. The DOM-level link takeover STAYS (it is the only
thing that can route an https link to the system browser by protocol, which
the host does not do) but now delegates to the host's browser tab via
ctx.sidebarRight.openTab('browser', …) with a window.open fallback, and the
two settings that only ever configured the plugin's own iframe (sandbox
escape hatch, loopback allowlist) go with it — along with the host-side
browser.probe route they fed.
Cards: the empty-pane welcome cards adopt the host's guide-capsule recipe
(0.5px l4 hairline, 24px radius, layer-1 fill, 56px floor, 14px/20px padding)
so the plugin's 'pick what opens here' surface reads as the same design as
DSH's own. A theme.spec guard pins the geometry and the token-only paint —
including that the upstream-only --dsw-alias-bg-l1/-l2 spellings (defined
nowhere, so their declarations are silently dropped upstream) never appear
here.
Also drops the dead state the removed features left behind (SidebarTab.pin,
nextTerminal, agentWaits, bottomOpenedOnce, the agent-tab helpers, the
pinned-tab memo key), re-points every test fixture that used them at
surviving equivalents, and prunes the specs of the deleted features.
The hairline outline I added to the colored tab glyphs reads as a thick stroke
in the live instance, so it goes: the glyphs stay exactly as the icon set draws
them, tinted only through the wrapper's token. What the feedback actually asked
for was the terminal SIZE, and that is all that remains — it renders a step
down (0.85x, floor 10px) because the VSCodicon terminal is a wide filled
rectangle that read heavier than its neighbours.
tests/builtins.spec.ts keeps pinning both readings (tasks = layers, terminal =
the shrunk VscTerminal with no style override), so the assertion now also
guards against an outline creeping back in.
Two glyphs read wrong in the live instance:
- Tasks shows subagent sessions AND the host's background jobs, so a checklist
glyph described a page that does not exist. `VscLayers` (sheets stacked, i.e.
work running behind the conversation) says what the page is; the amber token
stays, so it still reads as live activity.
- The terminal was the widest glyph in the set and the only bare fill in a
strip of the plugin's own 1.5px-stroked icons, which made it look like a
heavy foreign block. It now renders a step down (0.85x the strip size, floor
10px) and every colored tab glyph gets a hairline outline of its own ink
(`stroke: currentColor` + `non-scaling-stroke`, so the line stays one device
pixel across the sets' mixed 16- and 24-unit viewBoxes; `paint-order: stroke`
centres it on the fill edge instead of fattening the shape).
tests/builtins.spec.ts pins both readings by glyph identity (tasks = layers,
terminal = the shrunk, outlined VscTerminal), so a future swap has to argue
with a failing assertion rather than with a comment.
Gates: typecheck / lint green, pnpm test 127 files / 1343 passed / 9 skipped.
Issue #611 asked for file-type icons like the official explorer's, and #429
built a colored theme for them. DSH 0.1.5-rc.2 makes most of that work
unnecessary: `@deepseek-ai/dsh-client-ui-primitives` now exports
`FileTypeIcon` / `CodeFileIcon` with the host's own 48-type full-color code
artwork plus category-colored sheet glyphs (and its classifier behind them).
So the plugin renders the host's icons instead of shipping a color table, and
color becomes the only behaviour rather than an opt-in theme.
File icons (src/client/file-icons.tsx)
- `builtinFileIcon(path, size)` → `<FileTypeIcon path size />`; folders use the
host's folder category. The plugin's own per-extension VSCodicon map is gone.
- The public `registerFileIcon` API from #531 is unchanged and still outranks
the built-ins, so an external plugin can take over any row. One semantic
consequence, now documented and tested: because the host classifier covers
every path, a registered catch-all (`exts: []`) claims rows it used to lose
to the built-in map. An unregistered catch-all (the old icon theme's shape)
is unaffected.
- Nothing is lazy any more: the artwork lives in a platform module the client
already holds, so `lib/client-file-icons.js` and its 563-entry dataset (255
kB) are deleted outright — the core bundle grew by 10 kB (0.85 → 0.86 MB).
- `src/client/file-icon-theme.ts`, the `fileIconTheme` pref (prefs-shared /
config / client prefs), the settings-page select row and the six
`settingsFileIconTheme*` keys in all 20 dictionaries are removed with it.
Tab glyphs (src/client/builtins/tab-icons.tsx)
- Every built-in tab type now declares a colored glyph: files (the host's
folder artwork), changes/diff (commit), tasks (checklist), side chat
(discussion), terminal (shell), browser (globe).
- The color comes from a `--dsw-alias-*` token through a wrapper class, never
from a literal — the skin contract (§12) holds and `tests/theme.spec.ts`
enforces both halves (no literals in the module, every color declaration in
the stylesheet resolves to a token).
Native right Sidebar chips (src/client/native/tab-adapter.tsx)
- The host's tab definition has no icon field, but the
`sidebar.right.pane.tab.title` slot IS the chip's content, so the plugin
draws the glyph itself: an editor tab with a path shows that file's icon,
every other tab shows its descriptor's icon — the same `descriptor.icon` the
workbench strip and the guide capsules already render, so the three cannot
drift. The glyph is `aria-hidden`, which keeps the chip's accessible name
exactly the title the mount lane matches on.
Gates: typecheck / lint / check:consumer-types green; pnpm test 127 files /
1342 passed / 9 skipped (3 new chip cases, 1 rewritten built-in case).
Brings in the theme plumbing around #531's API — the `fileIconTheme` pref
thread, the settings row, the 20 dictionaries' keys and the theme loader's
test — so the working tree is a complete, green starting point before the
colored implementation is replaced.
Conflicts (three; resolved by taking this line's side where it had moved on):
- src/client/service.ts: the import block keeps `baseName, extOf` (the
`isNarrowWidth` import the theme branch needed belongs to its own
fresh-session seeding, which main has since rewritten) and the feature-list
doc comment keeps main's "v0.19.0 REMOVED 'floatWindows'" note while
adopting the sharper `fileIcons` wording (matched by exts / names /
folderNames).
- tests/plugin-shape.spec.ts and tests/prefs.spec.ts: main DELETED the store
seeding tests these files used to hold and rewrote the schema assertions
(the `SIDEBAR_PREFS_DEFAULTS` destructuring), so this line's side wins —
the theme branch's re-added blocks describe behaviour main no longer has.
Next commit removes `fileIconTheme` again along with the 563-entry dataset and
its lazy chunk: DSH 0.1.5-rc.2 exports the official `FileTypeIcon` artwork, so
the plugin renders the host's icons instead of shipping its own color table.
- docs/plans/2026-09-10-dsh-0.1.5-rc.2-adaptation.md: the adaptation plan —
the upstream rc.1 -> rc.2 delta per affected area, why there is no
plugin-side code change, and the CI failure taxonomy (A real Windows
timeouts, B the two silent worker deaths, C the mount lane's npm
ETARGET/OOM) with the evidence and the fix for each.
- AGENTS.md §2/§3: CI pins rc.2, the mount lane's npm flags and their reason
(floating transitives + staged prerelease publishing), the Windows lane's
bounded pool and why, and the primitives-dependencies note extended to rc.2.
- README.md / README_EN.md: support badge (v0.19.1, verified on rc.2), the
install section's stable-release note (rc.1 hosts need no upgrade — the peer
floor is unchanged) and a v0.19.1 changelog entry covering the two CI fixes.
- docs/external-plugin-guide.md: baseline line -> v0.19.1 / DSH 0.1.5-rc.1+,
verified on rc.2.
- Comment-only: `DSH 0.1.5-rc.1` -> `0.1.5-rc.1+` where the note describes a
behaviour that arrived in rc.1 and is unchanged in rc.2 (native guide
description rendering, in src/client/native/index.ts, src/client/service.ts
and the three specs that assert it).
Baseline moves to DSH 0.1.5-rc.1 — the 0.1.5 line's first release
candidate, and the npm `latest` dist-tag now: peer floor ^0.1.5-rc.1,
devDependency pins, the CI mount-lane pin and dsh.plugin.json engines
all follow. 0.1.5-alpha.2 users stay on v0.19.0-alpha.1.
The upstream delta from alpha.2 is small: 373 changed files, mostly
version bumps, sidebar preview polish and test snapshots. Exactly two
changes touch this plugin, and only one needs work:
- `SidebarRightGuideEntry.description` is back (optional). The native
guide renders it only while it lists at most 4 entries; a longer list
drops every description. The plugin restores `TabDescriptor.description`
and the six built-in `guideDesc*` lines (20 dictionaries) verbatim from
0b6ac5d^, but deliberately does NOT restore the old generic
`nativeGuideDesc` fallback: the host has no fallback of its own, so a
descriptor that declares none now ships no `description` field at all
and renders as a clean title-only capsule.
Consequence worth knowing: the plugin contributes six guide entries, so
the default composition is over the 4-entry limit and shows titles only.
The mount lane proves the restored field end to end by shrinking the
enabled set to three types through the plugin's own settings route
(scratch profile only) and requiring the Files capsule to grow its line.
- The built-in `files` type declares a guide description again and uses a
coloured folder glyph; the plugin owns that kind, so nothing to do.
Verified unchanged from alpha.2 (so nobody re-checks them): the global
main-panel model, the file address grammar (util/workspace-path changed
only its package.json), the native tab-body host contract (.paneBody is
still a block scroller with a definite height), the core/agent/session/
subagent host APIs and the ui-primitives export surface.
Restore caveat fixed in the lane: the settings route merges patches
key-wise, so undoing a temporary `tabsEnabled` change by posting the
original (empty) map leaves the disabled keys behind — the e2e restores
every key it touched explicitly.
Baseline moves to DSH 0.1.5-alpha.2 only (peer floor ^0.1.5-alpha.2,
CI pin, manifest engines); alpha.1 users stay on v0.19.0-alpha.0.
Host-contract changes handled:
- the native guide entry lost its `description` field (entries are
icon+title capsules now): `TabDescriptor.description` and the six
`guideDesc*` keys plus the `nativeGuideDesc` fallback are removed.
- the file address grammar changed: `fileAddressFor` always returns a
session-scoped address (absolute paths keep their leading `/`),
`parseFileAddress` is prefix-based and strips `?`/`#`. The plugin's
purity-gated mirror follows.
- global main panels replaced the `conversation` root slot with the
keyed `main` slot (`main.conversation`): the bottom workbench's
center-column locator now accepts both keys and skips
`display: contents` slot hosts.
Fixes a pre-existing fill bug the alpha.2 probe made obvious: the native
tab body host is a block scroller with a definite height, so tab roots
that only declared `flex: 1` collapsed to content height and the side
chat composer drifted off the pane bottom. The native adapter now wraps
every tab body in a `height: 100%` column flex host.
Also promotes the dependencies `dsh-client-ui-primitives@0.1.5-alpha.2`
dropped from its manifest (anser / shiki / mdast-util-* / micromark-* /
katex / @shikijs/langs) and the newly unmet `dsh-session-persistence`
peer into devDependencies.
The native new-tab list rendered one generic line ("opens in the DSH
sidebar") under every plugin entry, so six plugin rows read identically.
`TabDescriptor.description` now carries the real purpose (string or
locale-following thunk; absent falls back to the generic line), and the
six visible builtins declare theirs across all 20 dictionaries.
- service.ts: `TabDescriptor.description` + docs (guide §4.1, §0 row).
- native/: the guide entry's description follows the descriptor; the
`files` takeover reuses the editor's line.
- builtins: files / changes / tasks / side chat / terminal / browser.
- tests: builtins assert every visible type declares a distinct line;
the lifecycle test asserts descriptor lines (and the takeover reuse).
DSH 0.1.5 owns the right column (its native Sidebar hosts every tab type
this plugin registers), so the plugin's own right panel, its width drag /
new-session seed prefs, and the free-window feature are gone. The bottom
workbench is the only plugin-owned surface left, and its expand/collapse
control is registered into DSH's session-header utilities list slot (the
header's corner seat belongs to the native sidebar's own control).
- state: one `bottomSplits` tree; `makeDefaultState()` takes no arguments;
`toggleBottomPanel` / `openTabInBottomPane` are the only landing
reducers; `setBottomHeight` and `sanitizeState` share the
`CONVERSATION_MIN` cap (a persisted tall height no longer snaps on the
first drag).
- service: every landing in the workbench (creation or focus) expands it;
`SIDEBAR_FEATURES` drops `'floatWindows'`; the open/close/activate tab
pools cover the single tree.
- shell: `Sidebar.tsx` renders only the bottom workbench; the toggle lives
in `sidebar/bottom-toggle.tsx`; layout-push pushes height only (no width,
no `--dsh-sidebar-width`).
- prefs: `openByDefault` / `defaultWidthPercent` / `changesDiffFloat`
removed from the schema, defaults, client parser, settings page, and all
20 dictionaries; the retired keys in stored documents are ignored.
- tests: free-window specs deleted, panel/float assertions dropped,
remaining suites adapted (124 files / 1287 tests); the mount lane asserts
the header toggle and sweeps the native sidebar's guide page.
- docs: README / README_EN / guide §0,§11 / AGENTS test map.
- New persisted built-in pref workspaceFence (default true) under the
files card's secondary settings modal; host reads it per request via
the settings seam (fenceEnabledOf — absent/malformed stays ON).
- ensureWorkspacePath/ensureWorkspaceWritePath gain a fence param:
disarmed skips the containment assert but keeps realpath resolution;
wired through fs.tree/fs.read/fs.write, the media + html routes, and
the upload path (writeWorkspaceUpload fence input).
- Editor load failures and file-tree level errors show the localized
reason plus a one-click global off (FenceErrorNotice) that flips the
pref, adopts it into the store, and auto-retries the failed operation
(reloadSeq / retryDir) — the raw wire text is never shown.
- GitView's two client-side pre-checks (hidden open action + no-op
defense) respect the pref; store threaded through TreePanel/FileTree.
- i18n: 4 new keys across all 21 dictionaries; tests: fence-off route
coverage, prefs parsing, schema default, editor toggles list;
docs: guide §8/§8.1 + plans/2026-08-29 design record.
* feat(editor): file tree 'open with' submenu (external editors, pin, SSH-remote, custom editors)
The file tree right-click menu gains an 'Open with >' submenu with the
resource manager (reveal in file manager), VS Code, Cursor and Zed, plus
user-defined custom editors (name + URL template + VSCode-family flag).
Each submenu row carries a pushpin that promotes the target to a direct
top-level menu item.
A configurable SSH host (settings: Files card gear) switches VSCode-family
openers to <scheme>://vscode-remote/ssh-remote+<host>/<path> and hides
host-local targets (file manager / Zed / non-VSCode custom editors).
External opens run through the new fenced /sidebar/api/open.external route
which spawns the platform opener with an argv array (no shell); the client
never navigates raw scheme URLs itself. The settings seam's render panel now
appends after the declarative rows instead of replacing them.
* feat(editor): polish open-with menu UI — brand icons, pushpin, chevron, row alignment
- Submenu rows: the custom label is now a block-level flex row filling the
primitives itemLabel, so the pushpin docks at the row's far right (matching
the trailing check of every other menu); menu row icons normalized to 16px
(DSH native menus use 16, ours were 14).
- The submenu parent row gains a right-aligned chevron (the primitives Menu
renders no arrow for submenu parents).
- Icons via react-icons: codicons VscPin/VscPinned pushpins (replacing the
hand-drawn pin), VscFile/VscFolder/VscFolderOpened tree glyphs (replacing
the </> file mark), VscLinkExternal for the open-with parent and the
browser tab's open-external button (globally), SiCursor/SiZedindustries
brand silhouettes; the VS Code mark is inlined from simple-icons@11.0.0
(CC0) as IconVscode16 since later simple-icons releases dropped it. All
monochrome currentColor to follow the active skin.
- tsdown: pin react-icons si/vsc to their ESM entries via resolve.alias —
the package's exports map lists require before import, so the shared
conditionNames picked the unshakeable CJS entry and bloated the core
bundle by ~6.4 MB; tree-shaken it now adds only ~12 KB.
* feat(editor): merged explorer mode — path input, docked file tree, global name search
New editorExplorer pref (default on, editor card gear): the editor tab gains
a path-input header and a toggleable right-docked tree panel (per-tab state
in tab.meta.treeOpen; file tabs default closed, the seeded path-less home
tab defaults open). Fresh sessions seed that empty editor tab instead of
the explorer tab when merged mode is on; the standalone explorer tab stays
in the + menu unchanged.
- Extract FileTree.tsx from ExplorerView (shared by both hosts)
- Host fs.search route: recursive case-insensitive name search rooted at
the session cwd, budget-capped (200 matches / 100k visited), skips .git,
never descends symlink dirs
- EditorHost reads the pref reactively (boolean snapshot) and keeps the
pre-merge layout verbatim when off
* feat(settings): select row type for declarative settings; editorExplorer as iconed select
- SidebarSettingToggle gains type 'select' with options {value,title,desc,icon}
and multi (default false; stores the picked values as an array in options
order). Any option carrying an icon renders big-icon option cards in the
dropdown and the icon in the closed anchor; icon-less rows are one-line text.
- SelectRow in SideCardSection rides the primitives Menu (portal); single-pick
commits and closes, multi toggles and stays open. Wired for both host-prefs
toggles and plugin-owned pluginToggles via the new onSelectValue seam.
- The editorExplorer merged-mode pref is now an iconed select (merged vs
separate) instead of a switch; the stored value stays boolean.
- Advertise the capability as 'settingSelect' in SIDEBAR_FEATURES.
* feat(editor): unify explorer into the editor surface, resizable tree dock, hoisted toolbar
- One tree implementation, two presentations: the shared TreePanel (global
name search + refresh + FileTree) docks as the editor tab's right panel
and — in merged mode — fills the explorer tab's window; the pref-off
explorer keeps its legacy header shell.
- The docked panel drag-resizes from its left edge (160-480px clamp),
persisted as tab.meta.treeWidth alongside treeOpen.
- The text editor's preview/edit/save toolbar moves into the path-input
header row: FileViewerProps gains internal toolbar fields ('host' mode
skips the viewer's own row, reports EditorToolbarState and registers
EditorToolbarControls); non-merged mode is byte-identical to before.
* feat(editor): single files window with in-place switching; explorer descriptor removed
- editor tab replaces explorer on the + menu (order 10, Files); persisted
explorer tabs migrate to the editor home tab via sanitizeState
- editorExplorer now only controls open behavior: merged = in-place
updateTab, independent = openSidebarFile; both modes share the merged
chrome (path input + hoisted preview/edit/save toolbar + tree toggle)
- file tree context menu gains 'open in new tab' / 'open to the side'
(mintTabId avoids the id safety net; insertLeafAt splits right)
- tree dock resize uses pointer capture (touch-action none, 6px handle)
- defaults: openByDefault off, sidebar width 35%
- file tree clips horizontal overflow (no sideways scroll)
- e2e: mount lane arms the editor-chunk wait before goto and clicks the
tree row's left edge (hover @-reference button sits mid-row); drag lane
expands the panel first (collapsed push writes 0px), waits for the
slide-in to settle, and picks the leftmost col-resize strip; 'Files'
title assertions require draggable to skip the bottom panel's welcome
cards
* feat(editor): split mode turns the path-less window into the standalone explorer
In independent (split) mode a path-less files window renders ONLY the
tree panel (search + FileTree, full-window form) — no path input, no
hoisted toolbar, no tree toggle. File clicks open per-path editor tabs
(full chrome, tree docked closed by default) through openSidebarFile,
unchanged. Merged mode is untouched (chrome + docked tree, in-place
switching). TreePanel's previously reserved 'full' prop now has its
consumer.
