    - Add clear settings with good descriptions
    - Use `disableToggle: true` so users can turn it off if needed
    - Add helpful error messages if something goes wrong
+   - Use `beta: true` for experimental features to let users know they're trying something new

+## Plugin Metadata Options
+
+Your plugin object supports several optional flags to customize how it appears and behaves:
+
+```typescript
+const myPlugin: Plugin = {
+  id: "my-plugin",
+  name: "My Plugin",
+  description: "What my plugin does",
+  version: "1.0.0",
+  
+  // Optional flags:
+  disableToggle: true,     // Show enable/disable toggle in settings
+  defaultEnabled: false,   // Start disabled by default (requires disableToggle: true)
+  beta: true,             // Show "Beta" tag in settings UI
+  
+  // Your plugin code...
+  run: async (api) => { /* ... */ },
+};
+```
+
+- **`disableToggle`**: When `true`, users can enable/disable your plugin in settings
+- **`defaultEnabled`**: When `false`, your plugin starts disabled (only works with `disableToggle: true`)
+- **`beta`**: When `true`, shows an orange "Beta" tag next to your plugin name in settings
