## 🖼️ Feature Tour
-> All screenshots below are taken from the real UI (dark theme). Placeholder slots will be filled in over time.
+> Below are real UI screenshots.
### 🗂️ File Workbench: Explorer
-Lazy-loading directory tree, symlinks classified by target kind (directory links expand, dangling links flagged), global filename search, file/folder upload buttons plus drag-drop upload, context menu (open in new tab / open to the side / copy paths), and a hover `@file` button that references a file straight into the composer.
+Two explorer modes: embedded in the file preview / standalone file tree. Lazy-loading directory tree, symlinks classified by target kind (directory links expand, dangling links flagged), global filename search, file/folder upload buttons plus drag-drop upload, context menu (open in new tab / open to the side / copy paths), and a hover `@file` button that references a file straight into the composer.

-### ✍️ CodeMirror Editor
-
-Open per path (new tab) or switch in place (opt-in merged mode), preview / edit / save in one window, syntax highlighting for 20+ languages, `Ctrl/Cmd+S` to save.
-

+
+
### 📝 Inline Preview: Markdown · Images · PDF
The Markdown preview renders **Mermaid diagrams** (strict-mode safe rendering + a second sanitize pass; click a diagram for a zoom modal with wheel-zoom and drag-pan); images / PDFs display inline via the media route; the Office suite is covered by an ecosystem plugin.

### 💻 Real Terminal
xterm.js + node-pty real shell (not an emulator): transcript replay on reconnect, configurable shell / shellArgs (settings page or `cordis.patch.yml`), and optional `terminal_*` model tools so the agent can open terminals and run commands itself.
-
+
### 🌿 Git Panel
-Stage / unstage / commit (`Ctrl+Enter`) / revert, plus a history list; clicking a changed file opens a **VSCode-style diff tab** (line-level red/green). push / pull / fetch are covered by the ecosystem plugins [dsh-git-remotes](https://github.com/yq04/dsh-git-remotes) and [dsh-git-forge](https://github.com/thirsty5034/dsh-git-forge).

-
+
### 🌐 Embedded Browser
Multiple web tabs with back / forward / reload / address bar; content runs in an **opaque-origin sandboxed iframe** (live sandbox status in the UI, per-page temporary unlock available); external-link clicks in the chat can be taken over into the sidebar (protocol-based routing, configurable).
-
+
### 🧩 Tasks: Agent Topology + Background Jobs
Live subagent-tree topology (run states, batched live previews) plus the background-jobs list (exit codes / live output / force-kill); new subagents / jobs can auto-expand the sidebar (configurable).
-
+
### 💬 Side Chat (beta)
Codex-style side threads: **one independent tab per conversation**; the thread inherits the parent's full context (including the in-progress turn, honestly frozen as "interrupted") and runs independently without polluting the main session; follow-ups survive restarts; one click promotes the thread to a top-level session.
-
+
### 🪟 Dual Workbench: Sidebar + Bottom Panel + Split Panes
The right sidebar and the bottom panel can stay open together; drag a tab to a pane edge to **split**, to the middle to **merge** (works across panels); panel width/height drag from the left/top edge; on mobile everything merges into a full-width drawer.
-
-
-
+
### ⚙️ Declarative Settings
The "Side card" section in DSH settings: one small card per tab / viewer with an independent toggle (highlighted enabled state + brand switch); secondary settings open from the "Feature settings" strip at the card bottom (switch / text / number / select rows); plugin-owned settings persist under `pluginSettings`.
-
+
### 📱 Mobile
On narrow screens (<768px) the panels become a full-width drawer: bottom-panel tabs merge into the sidebar once, with touch-friendly dragging.
