UI Enhancements

Chat column width and alignment control, numbered question history with keyboard navigation and auto-load of older questions, and markdown outline rails for both the conversation and the file preview.

Shows every session theme in the DSH Web left sidebar immediately on page load by warming the session projection cache at startup; no need to click into a conversation first.

Smooth comet-mode animated caret for the DSH Web composer: a glowing comet trail replaces the native blinking caret and glides across the input as you type, with configurable accent color, thickness, and trail, IME-aware for CJK input.

Adds a non-uniform conversation density map(chat history markers) to the right of the DSH chat area: one tick per turn, with tick length and spacing reflecting message size, clickable to jump to a turn and expanding on hover when crowded.

Vertical message pointer rail on the left edge of the chat: one dash per user message, click to scroll to that message, hover for a preview bubble.

An Excalidraw prototyping tab for dsh-better-sidebar with structured product clarification, conflict-aware human and Agent board updates, and prototype-guided frontend generation.

Web chat entry for DeepSeek Harness: a sidebar button opening chat.deepseek.com in a dedicated desktop window under dsh-desktop, with in-webview fallback for plain web environments.

Web Composer placement for long prompts: keep it at the bottom or dock it in a resizable right column beside a long answer.

Lets you choose which items appear in the DeepSeek Harness settings left nav.

Adds a prompt-enhancement button to the DSH composer that rewrites drafts into agent-ready prompts.

Three-tier now/next/later input planning dock for the DeepSeek Harness web GUI: a red/yellow/green priority strip replaces the busy-Enter queue, plain Enter queues to later, with in-place multi-line editing, drag reorder, and session-isolated freeze/resume; the freeze button bridges a separate plugin, [dsh-session-guard](https://github.com/drscrewdriver/dsh-session-guard) (installable from dsh-market), via stopNextTurn/resume RPC + composer lock for a real per-session lock, pairing with its global peak-hour auto-pause to stop sessions during DeepSeek's high-cost windows and resume off-peak.

Preset-mode badge embedded in the "New Session" button: click to pick the default agent preset for the next session (long names truncate with ellipsis so the label stays readable).

Adds a "Work Roles" tab and a pixel-art office overlay to the DeepSeek Harness Web UI: 508 built-in role cards (The Agency 255 + agency-agents-zh 253) with search, EN/ZH toggle and department filter; draggable Canvas 2D pixel characters that stand, type and pace, with idle chat that can plug into AI. One-command npm install, no dsh source changes.

Preview Mermaid diagrams as images via local rendering in DSH Web when the chat message contains a Mermaid fenced code block, and also allow integration with external rendering servers.

Results-only conversation toggle for the Web GUI: hides thinking and tool-call process rows, keeps one live status line while the agent works, restores working animations under prefers-reduced-motion, zh-CN/en localized. Works in the stock composer and inside dsh-split-screen panes; verified on DSH 0.1.1 and 0.1.5.

**DeepSeek Chat (chat.deepseek.com) same-style attachments**: paperclip upload button, 240×64 DS-style file cards with official colored doc icons (PDF/DOCX/XLSX/PPT/IMG extracted from the DS frontend bundle), drag-and-drop, text extraction (PDF/DOCX/XLSX/TXT) injected into the message, and real attachment cards rendered in the transcript (custom user renderer) with the model reading full content.

Mobile UI for the Web GUI on narrow screens: full-width responsive layout, overlay session drawer, 44px touch targets, safe-area support, and reading enhancements with zero desktop impact.

Auto-saves large pasted text as an attachment file in the DeepSeek Harness web input box; with dsh-better-sidebar installed, the paste pill opens the file in the sidebar editor and saves it back.

Installs an image-input checkbox into the Models catalog so a custom model can declare image input and receive images directly; includes an optional BYO vision relay.

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

DSH Web right-side output dock: session-scoped tabs for reports, images, data, video, and audio, with inline previews, output quality checks, and a searchable per-turn history.

Windows one-click launcher with a borderless WPF startup animation (stroke-by-stroke HARNESS lettering) that starts dsh web in the background and fades into the GUI once ready, plus a desktop_launch tool.

Focus mode with a full-screen reading overlay that hides the header and composer and folds AI tool calls into summaries.
