Runs open-mcp-apps inside DSH: every MCP app gets its own sidebar container with a separate workspace, session, and App mode, an agent status strip under the app, and inline app rendering in ordinary chats.

Archived conversations list in the sidebar footer with read-only previews of the most recent messages, for sessions the product deliberately keeps hidden and unreopenable.

Zero-token online status indicator for the DeepSeek Harness web UI: an always-visible online/offline dot in the conversation header, auto-refreshed every 15 seconds with no LLM calls.

Shows the current conversation's working directory in a draggable directory panel with adjustable opacity.

Animated Claude-style reasoning-effort slider and model picker that replaces the native DSH model selector.

Client-only right-edge chat input index rail: one bar per user message, two-stage hover preview (15 chars, expandable to 40), click-to-jump, and scroll-follow highlight; static npm bundle with no host half.

Voice input for the web UI: a mic button in the composer that transcribes speech into the draft via the Web Speech API, with an optional auto-send toggle.

DSH plugin (dsh-desktop-launcher) that launches the dsh-desktop Windows Electron shell from the conversation: double-click to run the DSH web in a standalone window, region screenshot with GPU-accelerated selection that auto-pastes into the chat (works with vision bridges), system tray, session manager, auto environment setup, configurable port, single-instance lock.

Fully customizable keyboard shortcuts for the Web UI: 34 pre-registered features (sessions, views, clipboard, models, silent permission cycling, settings), one-click recording to bind your own, and a shortcut cheatsheet with built-in diagnostics.

Provider-tabbed model picker for the dsh web composer: left provider column and right model list, both independently scrollable, with cross-provider search.

Draggable 3D liquid-glass floating card for the DSH web GUI: DeepSeek API balance, cumulative spend/token stats (today/yesterday/7d/30d/all), adjustable glass/3D/color controls, and one-click top-up.

Optimize Prompt button under the composer: one click rewrites your draft into a clearer, more executable prompt, with a before-and-after dialog and one-click replacement.

Journals every AI file write/edit into before/after snapshots for an inline VS Code review flow (accept/reject hunks, per-file undo, no git).

Mobile adaptation for the DSH Web UI on narrow screens: reveal drawer with the chat layer on top, drag gestures, bottom-sheet settings panel, composer and header fixes, zero desktop impact.

Adds searchable filtering to the model selector by provider, model name, and model ID; spaces act as wildcards.

Drag & drop or click to attach any non-image file (PDF/Word/Excel/ZIP/text) into the composer: in the desktop shell it resolves the real Finder path instantly; otherwise it uploads to the workspace and inserts the path.

PBR 3D model preview for game art: GLB/GLTF with textures, IBL environment lighting, orbit controls, and a material channel inspector (baseColor/normal/roughness/metallic/AO/emissive/wireframe); scalar channels shown as grayscale per PBR spec, via the pbr3d fence and pbr_render tool.

Line-range selection: browse workspace files, preview code with line numbers, visually select a line range, and write a `@path:start-end` reference into the composer; the agent receives the exact selected lines on send.

Control the Web UI left sidebar width: lower the 264px drag minimum and optionally tune the drag maximum and the expanded default width, applied by a startup patch of the ui-layout bundle.

Real PTY terminal panel for the DSH Web UI: host half spawns shells with node-pty (cmd.exe default on Windows), rendered in the browser with xterm.js; multi-tab sessions, dock/floating window, clipboard support.

A green interrupt button beside the send box: silently stops a running agent, which then summarizes its progress and asks for your new requirements, with a customizable interrupt prompt.

Full-duplex voice mode for the Web UI: a composer mic (RMS endpoint detection) transcribes speech with whisper running locally in the browser, assistant replies stream back as spoken audio sentence-by-sentence, and speaking interrupts playback and the running turn (true barge-in). No API key.

One-click start/stop button pinned to the window bottom-right corner: restarts DeepSeek Harness in place via a detached helper that relaunches the exact boot invocation (loopback same-origin guarded), with an optional stop-only action.

No-setup mode for the DSH web UI: hides advanced surfaces, auto-applies best defaults (chat mode, full access, account balance), and one-click role-play personas (maid/butler).
