+# Folder Bookmark Tray
+
+A Windows system-tray app for bookmarking folder paths with quick-action buttons (Explorer, Terminal, Claude, Visual Studio).
+
+Personal utility, Windows-only.
+
+## Screenshots
+
+_TBD — drop popup + context-menu screenshots in `assets/` and link them here._
+
+## Install / dev / build
+
+```sh
+npm install            # also runs `npm run icon` to generate the tray PNG
+npm run dev            # Vite (5173) + Electron, hot reload
+npm run build          # vite build → dist/
+npm run start          # run Electron against built dist/
+npm run dist           # build + electron-builder NSIS installer → build/
+npm run icon           # regenerate assets/tray-icon.png
+```
+
+## Usage
+
+- **Left-click** the tray icon → popup with the bookmark list. Each row shows alias + path + four action buttons and a `⋯` overflow menu (Copy path / Edit / Remove).
+- **Right-click** the tray icon → native context menu. Each bookmark is a submenu with the same actions, plus **Browse for folder…** (quick-add via folder picker) and **Manage…** (opens the popup).
+- **Pin toggle** in the popup header keeps it open after focus loss; pinned position is persisted across runs.
+- **Auto-fitting popup**: width is fixed at 360px; height grows with content from 180px up to a 600px cap, then scrolls internally.
+
+## Action buttons
+
+| Button | Behavior |
+|---|---|
+| 📁 Explorer | `shell.openPath(path)` |
+| `>_` Terminal | `wt.exe -d <path>` (Windows Terminal); falls back to `cmd.exe` on `ENOENT` |
+| `C` Claude | `cmd.exe /c start "" /D <path> cmd.exe /K claude` (detached, ignored stdio, unref'd) |
+| `VS` Visual Studio | Finds the first `*.sln` in the folder and opens it via shell association — uses whichever VS the user has registered for `.sln`. Disabled with a tooltip when no `.sln` is present. |
+| Copy path | `clipboard.writeText(path)` |
+
+## Config file
+
+Persisted to `app.getPath('userData')/config.json`. On Windows that's:
+
+```
+%APPDATA%\Folder Bookmark Tray\config.json
+```
+
+Schema:
+
+```ts
+{
+  bookmarks: [
+    { id: "uuid", alias: "string", path: "string", createdAt: "ISO8601" }
+  ],
+  pinned: false,
+  pinnedBounds?: { x, y },   // remembered drag position when pinned
+  popupHeight?: number       // last auto-fit height, clamped 180..600
+}
+```
+
+## Layout
+
+```
+electron/
+  main.js          tray + popup window + IPC handlers + context menu
+  preload.js       contextBridge → window.bookmarks
+  launchers.js     Explorer / Terminal / Claude / Visual Studio / clipboard / folder inspect
+src/
+  main.jsx, App.jsx
+  components/
+    Popup.jsx              ResizeObserver auto-fits Electron window height
+    BookmarkList.jsx
+    BookmarkRow.jsx        view + inline edit, ⋯ menu, VS-disabled-when-no-sln
+    AddBookmarkForm.jsx
+  styles/index.css
+scripts/generate-icon.js   produces assets/tray-icon.png at install time
+assets/tray-icon.png       orange folder pictogram, 32×32
+```
+
+## Stack
+
+Electron 33, React 18, Vite 5. NSIS installer via `electron-builder` (`appId: com.dbeuttel.folder-bookmark-tray`). No native deps.
+
+## Non-goals
+
+- macOS / Linux support
+- Cloud sync of bookmarks
+- Drag-to-reorder
+- Tagging or folder grouping
+
+## Why this exists
+
+Sibling utility to [`claude-usage-tray`](../ClaudeTracker) — same window chrome, same dark-theme tokens, same `userData/config.json` persistence pattern, same tray-anchored popup behavior. Where ClaudeTracker is a usage dashboard with a saved-paths side feature, this app makes folder bookmarks the whole point: a fast keyboard-free way to jump from the tray into Explorer, a terminal, Claude, or Visual Studio at a known directory.
