+# Paarrot Plugin System
+
+The Paarrot desktop client includes a powerful plugin system that allows you to extend and customize your Matrix experience.
+
+## What are Plugins?
+
+Plugins are small JavaScript modules that run inside Paarrot and can:
+- Add custom commands
+- Modify the UI
+- React to Matrix events
+- Add new settings sections
+- Enhance functionality
+
+## Installing Plugins
+
+### From the Plugin Marketplace
+
+1. Open **Settings** → **Plugins**
+2. Browse the **Marketplace** tab
+3. Click **Install** on any plugin you want to add
+4. The plugin will be downloaded and enabled automatically
+
+### Manual Installation
+
+1. Download a plugin ZIP file
+2. Extract it to your plugins directory:
+   - **Windows**: `%APPDATA%\paarrot\plugins\`
+   - **Linux**: `~/.config/Paarrot/plugins/`
+   - **macOS**: `~/Library/Application Support/Paarrot/plugins/`
+3. Restart Paarrot
+4. Enable the plugin in **Settings** → **Plugins** → **Installed**
+
+## Managing Plugins
+
+### Viewing Installed Plugins
+
+Go to **Settings** → **Plugins** → **Installed** to see all installed plugins.
+
+### Enabling/Disabling Plugins
+
+Click the toggle switch next to any plugin to enable or disable it. Disabled plugins won't run or use resources.
+
+### Uninstalling Plugins
+
+Click the **Uninstall** button next to any plugin to remove it completely.
+
+### Searching Plugins
+
+Use the search bar to filter plugins by name, description, author, or tags.
+
+## Plugin Security
+
+⚠️ **Important Security Information**
+
+Plugins run with access to your Matrix client and can:
+- Read your messages
+- Send messages on your behalf
+- Access your room list
+- Modify app behavior
+
+**Only install plugins from trusted sources!**
+
+### Safety Tips
+
+1. **Check the author**: Install plugins from known developers
+2. **Read reviews**: Look for community feedback
+3. **Review permissions**: Understand what the plugin can do
+4. **Keep updated**: Update plugins regularly for security fixes
+5. **Report issues**: If a plugin behaves suspiciously, report it immediately
+
+## Developing Plugins
+
+Want to create your own plugin? Check out the [Plugin Development Guide](./cinny/src/app/features/settings/plugins/PLUGIN_DEVELOPMENT.md).
+
+### Quick Start
+
+1. Create a plugin directory with:
+   - `index.js` - Your plugin code
+   - `plugin-metadata.json` - Plugin information
+
+2. Implement the plugin interface:
+```javascript
+module.exports = {
+  onLoad: async (context) => {
+    // Your plugin initialization
+    console.log('Plugin loaded!');
+  },
+  onUnload: async () => {
+    // Cleanup when disabled
+  }
+};
+```
+
+3. Test locally by copying to your plugins directory
+
+4. Publish to the [Plugin Directory](https://github.com/Paarrot/Plugin-Directory)
+
+## Plugin API
+
+Plugins have access to:
+- **Matrix Client**: Full matrix-js-sdk client instance
+- **React**: For building UI components
+- **Commands**: Register custom slash commands
+- **UI Hooks**: Inject UI elements
+- **Settings**: Add custom settings sections
+- **Utilities**: Notifications and helpers
+
+See the [Plugin Development Guide](./cinny/src/app/features/settings/plugins/PLUGIN_DEVELOPMENT.md) for complete API documentation.
+
+## Example Plugins
+
+Check out the `example-plugin/` directory for a simple example demonstrating:
+- Matrix client access
+- Event listeners
+- Custom commands
+- Notifications
+
+## Troubleshooting
+
+### Plugin Won't Load
+
+1. Check the browser console for errors (F12 → Console)
+2. Look for `[PluginLoader]` messages
+3. Verify `index.js` exists in the plugin directory
+4. Ensure `plugin-metadata.json` is valid JSON
+
+### Plugin Crashes
+
+1. Disable the plugin in Settings → Plugins
+2. Check console for error stack traces
+3. Report the issue to the plugin author
+4. Try reinstalling the plugin
+
+### Performance Issues
+
+If Paarrot becomes slow:
+1. Disable plugins one by one to identify the culprit
+2. Check for memory leaks in the console
+3. Contact the plugin author with details
+
+## Plugin Directory
+
+The official Paarrot Plugin Directory is maintained at:
+https://github.com/Paarrot/Plugin-Directory
+
+Submit your plugins there to make them available in the marketplace!

+# Plugin System Wishlist - Implementation Summary
+
+All requested features have been implemented! 🎉
+
+## ✅ Implemented Features
+
+### 1. ✅ Enhanced Slash Commands
+- **Simple commands**: `ctx.commands.register({ name: "shrug", run: () => "¯\\_(ツ)_/¯" })`
+- **Commands with args**: `ctx.commands.register({ name: "echo", args: ["text"], run: ({ text }) => text })`
+- Automatic argument parsing
+- Execution API: `ctx.commands.execute(name, args)`
+
+### 2. ✅ Message Interceptors
+- **Before send**: `ctx.messages.onBeforeSend((msg) => { msg.content = "modified" })`
+- **On receive**: `ctx.messages.onReceive((msg) => { /* process */ })`
+- Full MessageContext with content, roomId, metadata
+- Async support for interceptors
+
+### 3. ✅ Custom Renderers
+- **Register**: `ctx.ui.registerRenderer("message", (msg, defaultRenderer) => { /* render */ })`
+- **Unregister**: `ctx.ui.unregisterRenderer("message")`
+- Fallback to default renderer support
+- Discord-mod-tier customization enabled
+
+### 4. ✅ Settings UI Per Plugin
+- **Define schema**: `ctx.settings.define({ theme: { type: "select", options: [...] } })`
+- **Supported types**: string, number, boolean, select, color
+- **Get/Set**: `ctx.settings.get(key)` / `ctx.settings.set(key, value)`
+- Auto-persisted to localStorage
+- No JSON editing needed!
+
+### 5. ✅ Hot Reload
+- **API**: `pluginRegistry.reloadPlugin(pluginId, newPlugin, newContext)`
+- Auto-cleanup of old plugin resources
+- Maintains enabled/disabled state
+- Dev-friendly workflow
+
+### 6. ✅ Dependency System
+- **Declare**: `dependencies: { "paarrot.core-utils": "^1.0.0" }`
+- **Require**: `const utils = ctx.require("paarrot.utils")`
+- Error handling for missing dependencies
+- Plugin exports system
+
+### 7. ✅ Raw Matrix Events Hook
+- **Full SDK access**: `ctx.matrix.on("m.room.message", (ev) => { })`
+- **Any event type**: Room.timeline, sync, RoomState.events, etc.
+- Direct Matrix.js SDK integration
+- Power users will go nuts!
+
+### 8. ✅ Background Tasks / Intervals
+- **Interval**: `ctx.timers.setInterval(() => { /* cursed shit */ }, 10000)`
+- **Timeout**: `ctx.timers.setTimeout(() => { }, 5000)`
+- **Clear**: `ctx.timers.clearInterval(id)` / `ctx.timers.clearTimeout(id)`
+- Auto-cleanup on plugin unload
+- Perfect for bots, reminders, auto-cleanup
+
+### 9. ✅ Notifications API
+- **Simple**: `ctx.notify("Oi")`
+- **Advanced**: `ctx.notify({ title: "Oi", body: "New message from Steve", type: "info" })`
+- Action buttons support
+- Custom duration
+
+### 10. ✅ Plugin Logs Panel
+- **Logging**: `ctx.log()`, `ctx.warn()`, `ctx.error()`
+- Per-plugin log storage
+- Visible in `pluginRegistry.getLogs(pluginId)`
+- Cleared on plugin unload
+- Max 1000 logs retained
+
+## 🎯 Bonus Features
+
+- **Plugin exports**: Share functionality between plugins
+- **Automatic cleanup**: Timers, handlers, resources auto-cleaned on unload
+- **Error isolation**: Plugin errors don't crash the app
+- **Type safety**: Full TypeScript definitions
+- **Sandboxed execution**: Plugins run in controlled environment
+- **Rich context**: Full Matrix client, React, all APIs
+

+## 🎨 Plugin API Summary
+
+```typescript
+interface PluginContext {
+  pluginId: string;
+  matrixClient: MatrixClient;
+  React: typeof import('react');
+  
+  commands: {
+    register: (command: PluginCommand) => void;
+    unregister: (name: string) => void;
+    execute: (name: string, args: Record<string, any>) => Promise<string | void>;
+  };
+  
+  messages: {
+    onBeforeSend: (interceptor: MessageInterceptor) => void;
+    onReceive: (interceptor: MessageInterceptor) => void;
+  };
+  
+  ui: {
+    registerRenderer: (type: string, renderer: CustomRenderer) => void;
+    unregisterRenderer: (type: string) => void;
+  };
+  
+  settings: {
+    define: (schema: SettingsSchema) => void;
+    get: <T = any>(key: string) => T | undefined;
+    set: (key: string, value: any) => void;
+  };
+  
+  matrix: {
+    on: (eventType: string, handler: (event: MatrixEvent) => void) => void;
+    off: (eventType: string, handler: (event: MatrixEvent) => void) => void;
+  };
+  
+  timers: {
+    setInterval: (callback: () => void, ms: number) => number;
