Compact right-edge turn rail with hover summaries and click-to-jump navigation.

System status floating widget: live CPU/memory/disk usage in the bottom-right corner of the DSH Web UI with threshold colour warnings.

LAN mobile gateway: isolated child-process reverse proxy with first-visit approval, per-device token binding, rate limiting, and mobile layout injection (compact composer pills, randomUUID polyfill).

One-click collapse of every expanded section (Think rows, tool cards) with a live-count pill and a customizable hotkey.

A 60-frame theme-aware monochrome whale-dive animation with reactive water for the DSH Web turn status: embedded assets, seamless closed-loop playback, a reduced-motion PNG fallback, and lifecycle-clean removal.

Windows tray desktop shell: auto-installs and auto-updates the exe from GitHub Releases, creates desktop shortcuts for both the app and the web UI, and exposes a desktop_launch tool to start it from the conversation.

Semantic UI sound effects powered by uisfx: task start/success/failure and per-button cues, settings UI with instant preview, 12 sound packs, Host-persisted preferences, and `ctx.uisfx` service for other plugins.

Session timeline down the left of the conversation: every user message at a glance, current-message tracking, hover preview of the message and its reply, click to jump, collapsible.

Document reading mode for DSH.

Pomodoro focus-and-break timer for DSH Web with configurable cycles, a draggable mini panel, and in-app, sound, and browser notifications.

Use DSH from iPhone/iPad: an explicit-opt-in LAN reverse proxy (Host/Origin rewrite through the loopback trust fence, WebSocket upgrades included), iOS PWA chrome (home-screen icon, standalone meta, viewport-fit), and touch/mobile CSS (safe areas, keyboard lifting, composer row fit).

Codex Pets-style floating pixel pet with 10 built-in Petdex-compatible pets, a 9-state agent-status engine (idle/running/waiting/review/failed plus client-side waving/jumping/directions), draggable overlay, pet picker/zoom settings, notification bubbles, and a `pet_say` tool for the agent to speak through the pet.

Deep links: open a specific session or workspace via `?session=` / `?workspace=`.

The generic New Session action opens a default-directory workspace instead of requiring a folder pick, and the workspace picker lists that workspace as a no-folder choice.

Client-side writing panel for the Web UI: project volumes and stats, corpus library, full-text search, evolution version-chain diffs, and an SVG thread graph, shown only in writing-preset sessions.

Highlights parts of speech (nouns green, verbs red, adjectives/adverbs purple) in rendered DSH Web Markdown, with light/dark palettes, toggles, and stream-aware updates.

Settings -> Plugins switchboard: every loaded plugin card shows its package description and runtime phase, with fuzzy search and start/stop toggles that never rewrite config files.

A floating command deck that lists every slash command in DeepSeek Harness as runnable buttons, sorted by usage.

UI butler for every plugin UI: official/plugin categories, per-widget toggles, drag move/resize, collision avoidance and one-click auto arrange.

Claude-style drag-and-drop/paperclip file upload with content sniffing, document-to-Markdown via Microsoft MarkItDown (built-in JS fallback), text inlining, and a read_document tool for agents.

Projection-driven live DAG for a Session's subagents and durable workflows: status and navigation, deterministic deep-chain layout, fit/pan canvas controls, and current-session node rearrangement.

DSH Web right-side output dock that collects session artifacts, previews user-facing files, and preserves tab state per session.

Codex-style tool call folding, collapsing multiple tool calls into a single line.

Workspace file tree for the Web UI: multi-tab preview (text/DOCX/PDF/Markdown/CSV/images), inline Markdown editing, a Git changes panel, and file operations (rename/delete/copy/move/create) via context menu.
