Plugins

Standalone wallpaper background for the DSH Web UI and desktop app: built-in wallpapers, local image/video uploads stored in IndexedDB, and a read-only local Wallpaper Engine library served by the bundled wallpaper-engine-api service in the repository; renders images, video and scene workshop previews, with light-fog/dark-overlay, blur, brightness and safe-zoom controls plus a read-only follow-desktop-wallpaper mode.

Persists unsent composer attachments per session, so images and files pasted into the input box survive page switches, conversation switches and app restarts: the bytes are mirrored in IndexedDB and handed back through the official createDrafts/addAttachments channel, and are dropped as soon as the message is sent or you remove them.

dsh-skin 增强版：为 DeepSeek Harness 提供皮肤切换与自定义背景壁纸。在原版基础上修复了两处问题——① 大图/特殊格式上传无响应（改用 createImageBitmap 直接解码、增加处理中与错误提示）；② 主题切换时 overrideTokens 触发 theme/change 导致无限递归栈溢出（加皮肤/明暗守卫断开循环）。壁纸存储从 localStorage 压缩方案改为 IndexedDB 原文件直存，全画质显示、零压缩，并自动迁移旧数据。

Renders mermaid and mmd code fences in DSH messages as diagram cards with zoom, pan, a full-screen viewer and SVG export, caching each render in memory and IndexedDB so the same diagram is not drawn twice.

Human-only browser panel that opens as a full page in the DSH main content area: multiple tabs, an address bar, a context menu, a homepage with pinned shortcuts, and a history page stored in IndexedDB. Pages render in the webview bridge that ships with DSH Desktop, and the current page can be opened in your local Chrome.

Adds a notepad to the DSH Web UI that floats as an edge-snapping, resizable card or docks into the real bottom layout row, switchable at runtime with shared text and images; notes auto-save (text in localStorage, images in IndexedDB) and follow the active theme.

Read EPUB, PDF, DRM-free MOBI/AZW3 and TXT in the DSH sidebar. WeChat Read style typography with TOC, bookmarks, highlights and progress memory; select any passage to translate it into Chinese; the Ask-the-Book AI answers only from passages retrieved from the open book. Books and progress stay in local IndexedDB. Four themes including an eye-care green paper, and PDF paper follows the theme.

Private relationship notebook: scores each day of chat from message-level evidence and tracks how the relationship develops over time. Chats, profiles and drafts stay in your browser's local IndexedDB and the plugin runs no server of its own, but using model replies, profiling or automatic analysis sends the relevant chat context to the model service configured in DSH.

Chat wallpaper: use a local image, a local video or one of six preset gradients as the chat background, with clarity, opacity, zoom, position, dark veil, fit mode, motion and glass panels; files stay in IndexedDB and nothing is uploaded.
