+# LauncherExample Plugin
+
+A demonstration plugin that showcases the DMS launcher plugin system capabilities.
+
+## Purpose
+
+This plugin serves as a comprehensive example for developers creating launcher plugins for DMS. It demonstrates:
+
+- **Plugin Structure**: Proper manifest, launcher, and settings components
+- **Trigger System**: Customizable trigger strings for plugin activation (including empty triggers)
+- **Item Management**: Providing searchable items to the launcher
+- **Action Execution**: Handling different types of actions (toast, copy, script)
+- **Settings Integration**: Configurable plugin settings with persistence
+
+## Features
+
+### Example Items
+- **Test Items 1-3**: Demonstrate toast notifications
+- **Copy Action**: Shows clipboard integration
+- **Script Action**: Demonstrates command execution
+
+### Trigger System
+- **Default Trigger**: `#` (configurable in settings)
+- **Empty Trigger Option**: Items can always be visible without needing a trigger
+- **Usage**: Type `#` in launcher to filter to this plugin (when trigger is set)
+- **Search**: Type `# test` to search within plugin items
+
+### Action Types
+- `toast:message` - Shows toast notification
+- `copy:text` - Copies text to clipboard
+- `script:command` - Executes shell command (demo only)
+

+├── LauncherExampleLauncher.qml    # Main launcher component
+├── LauncherExampleSettings.qml    # Settings interface
+└── README.md                      # This documentation
+```
+
+## Installation
+
+1. **Plugin Directory**: Copy to `~/.config/DankMaterialShell/plugins/LauncherExample`
+2. **Enable Plugin**: Settings → Plugins → Enable "LauncherExample"
+3. **Configure**: Set custom trigger in plugin settings if desired
+
+## Usage
+
+### With Trigger (Default)
+1. Open launcher (Ctrl+Space or launcher button)
+2. Type `#` to activate plugin trigger
+3. Browse available items or add search terms
+4. Press Enter to execute selected item
+
+### Without Trigger (Empty Trigger Mode)
+1. Enable "No trigger (always show)" in plugin settings
+2. Open launcher - plugin items are always visible
+3. Search works normally with plugin items included
+4. Press Enter to execute selected item
+
+### Search Examples
+- `#` - Show all plugin items (with trigger enabled)
+- `# test` - Show items matching "test"
+- `# copy` - Show items matching "copy"
+- `test` - Show all items matching "test" (with empty trigger enabled)
+
+## Developer Guide
+
+### Plugin Contract
+
+**Launcher Component Requirements**:
+```qml
+// Required properties
+property var pluginService: null
+property string trigger: "#"
+
+// Required signals
+signal itemsChanged()
+
+// Required functions
+function getItems(query): array
+function executeItem(item): void
+```
+
+**Item Structure**:
+```javascript
+{
+    name: "Item Name",           // Display name
+    icon: "icon_name",           // Material icon
+    comment: "Description",      // Subtitle text
+    action: "type:data",         // Action to execute
+    categories: ["PluginName"]   // Category array
+}
+```
+
+**Action Format**: `type:data` where:
+- `type` - Action handler (toast, copy, script, etc.)
+- `data` - Action-specific data
+
+### Settings Integration
+```qml
+// Save setting
+pluginService.savePluginData("pluginId", "key", value)
+
+// Load setting
+pluginService.loadPluginData("pluginId", "key", defaultValue)
+```
+
+### Trigger Configuration
+
+The trigger can be configured in two ways:
+
+1. **Empty Trigger** (No Trigger Mode):
+   - Check "No trigger (always show)" in settings
+   - Saves `trigger: ""` and `noTrigger: true`
+   - Items always appear in launcher alongside regular apps
+
+2. **Custom Trigger**:
+   - Enter any string (e.g., `#`, `!`, `@`, `!ex`)
+   - Uncheck "No trigger" checkbox
+   - Items only appear when trigger is typed
+
+### Manifest Structure
+```json
+{
+    "id": "launcherExample",
+    "name": "LauncherExample",
+    "type": "launcher",
+    "capabilities": ["launcher"],
+    "component": "./LauncherExampleLauncher.qml",
+    "settings": "./LauncherExampleSettings.qml",
+    "permissions": ["settings_read", "settings_write"]
+}
+```
+
+Note: The `trigger` field in the manifest is optional and serves as the default trigger value.
+
+## Extending This Plugin
+
+### Adding New Items
+```qml
+function getItems(query) {
+    return [
+        {
+            name: "My Item",
+            icon: "custom_icon",
+            comment: "Does something cool",
+            action: "custom:action_data",
+            categories: ["LauncherExample"]
+        }
+    ]
+}
+```
+
+### Adding New Actions
+```qml
+function executeItem(item) {
+    const actionParts = item.action.split(":")
+    const actionType = actionParts[0]
+    const actionData = actionParts.slice(1).join(":")
+
+    switch (actionType) {
+        case "custom":
+            handleCustomAction(actionData)
+            break
+    }
+}
+```
+
+### Custom Trigger Logic
+```qml
+Component.onCompleted: {
+    if (pluginService) {
+        trigger = pluginService.loadPluginData("launcherExample", "trigger", "#")
+    }
+}
+
+onTriggerChanged: {
+    if (pluginService) {
+        pluginService.savePluginData("launcherExample", "trigger", trigger)
+    }
+}
+```
+
+## Best Practices
+
+1. **Unique Triggers**: Choose triggers that don't conflict with other plugins
+2. **Clear Descriptions**: Write helpful item comments
+3. **Error Handling**: Gracefully handle action failures
+4. **Performance**: Return results quickly in getItems()
+5. **Cleanup**: Destroy temporary objects in executeItem()
+6. **Empty Trigger Support**: Consider if your plugin should support empty trigger mode
+
+## Testing
+
+Test the plugin by:
+1. Installing and enabling in DMS
+2. Testing with trigger enabled
+3. Testing with empty trigger (no trigger mode)
+4. Trying each action type
+5. Testing search functionality
+6. Verifying settings persistence
+
+This plugin provides a solid foundation for building more sophisticated launcher plugins with custom functionality!

+## Launcher Plugins
+
+Launcher plugins extend the DMS application launcher by adding custom searchable items with trigger-based filtering.
+
+### Overview
+
+Launcher plugins enable you to:
+- Add custom items to the launcher/app drawer
+- Use trigger strings for quick filtering (e.g., `!`, `#`, `@`)
+- Execute custom actions when items are selected
+- Provide searchable, categorized content
+- Integrate seamlessly with the existing launcher
+
+### Plugin Type Configuration
+
+To create a launcher plugin, set the plugin type in `plugin.json`:
+
+```json
+{
+    "id": "myLauncher",
+    "name": "My Launcher Plugin",
+    "type": "launcher",
+    "capabilities": ["launcher"],
+    "component": "./MyLauncher.qml",
+    "settings": "./MySettings.qml",
+    "permissions": ["settings_read", "settings_write"]
+}
+```
+
+### Launcher Component Contract
+
+Create `MyLauncher.qml` with the following interface:
+
+```qml
+import QtQuick
+import qs.Services
+
+Item {
+    id: root
+
+    // Required properties
+    property var pluginService: null
+    property string trigger: "#"
+
+    // Required signals
+    signal itemsChanged()
+
+    // Required: Return array of launcher items
+    function getItems(query) {
+        return [
+            {
+                name: "Item Name",
+                icon: "icon_name",
+                comment: "Description",
+                action: "type:data",
+                categories: ["MyLauncher"]
+            }
+        ]
+    }
+
+    // Required: Execute item action
+    function executeItem(item) {
+        const [type, data] = item.action.split(":", 2)
+        // Handle action based on type
+    }
+
+    Component.onCompleted: {
+        if (pluginService) {
+            trigger = pluginService.loadPluginData("myLauncher", "trigger", "#")
+        }
+    }
+}
+```
+
+### Item Structure
+
+Each item returned by `getItems()` must include:
+
+- `name` (string): Display name shown in launcher
+- `icon` (string): Material Design icon name
+- `comment` (string): Description/subtitle text
+- `action` (string): Action identifier in `type:data` format
+- `categories` (array): Array containing your plugin name
+
+### Trigger System
+
+Triggers control when your plugin's items appear in the launcher:
+
+**Empty Trigger Mode** (No trigger):
+- Items always visible alongside regular apps
+- Search includes your items automatically
+- Configure by saving empty trigger: `trigger: ""`
+
+**Custom Trigger Mode**:
+- Items only appear when trigger is typed
+- Example: Type `#` to show only your plugin's items
+- Type `# query` to search within your plugin
+- Configure any string: `#`, `!`, `@`, `!custom`, etc.
+
+### Trigger Configuration in Settings
+
+Provide a settings component with trigger configuration:
+
+```qml
+import QtQuick
+import QtQuick.Controls
+import qs.Widgets
+
+FocusScope {
+    id: root
+
+    property var pluginService: null
+
+    Column {
+        spacing: 12
+
+        CheckBox {
+            id: noTriggerToggle
+            text: "No trigger (always show)"
+            checked: loadSettings("noTrigger", false)
+
+            onCheckedChanged: {
+                saveSettings("noTrigger", checked)
+                if (checked) {
+                    saveSettings("trigger", "")
+                } else {
+                    saveSettings("trigger", triggerField.text || "#")
+                }
+            }
+        }
+
+        DankTextField {
+            id: triggerField
+            visible: !noTriggerToggle.checked
+            text: loadSettings("trigger", "#")
+            placeholderText: "#"
+
+            onTextEdited: {
+                saveSettings("trigger", text || "#")
+            }
+        }
+    }
+
+    function saveSettings(key, value) {
+        if (pluginService) {
+            pluginService.savePluginData("myLauncher", key, value)
+        }
+    }
+
+    function loadSettings(key, defaultValue) {
+        if (pluginService) {
+            return pluginService.loadPluginData("myLauncher", key, defaultValue)
+        }
+        return defaultValue
+    }
+}
+```
+
+### Action Execution
+
+Handle different action types in `executeItem()`:
+
+```qml
+function executeItem(item) {
+    const actionParts = item.action.split(":")
+    const actionType = actionParts[0]
+    const actionData = actionParts.slice(1).join(":")
+
+    switch (actionType) {
+        case "toast":
+            if (typeof ToastService !== "undefined") {
+                ToastService.showInfo("Plugin", actionData)
+            }
+            break
+        case "copy":
+            // Copy to clipboard
+            break
+        case "script":
+            // Execute command
+            break
+        default:
+            console.warn("Unknown action:", actionType)
+    }
+}
+```
+
+### Search and Filtering
+
+The launcher automatically handles search when:
+
+**With empty trigger**:
+- Your items appear in all searches
+- No prefix needed
+
+**With custom trigger**:
+- Type trigger alone: Shows all your items
+- Type trigger + query: Filters your items by query
+- The query parameter is passed to your `getItems(query)` function
+
+Example `getItems()` implementation:
+
+```qml
+function getItems(query) {
+    const allItems = [
+        {name: "Item 1", ...},
+        {name: "Item 2", ...},
+        {name: "Test Item", ...}
+    ]
+
+    if (!query || query.length === 0) {
+        return allItems
+    }
+
+    const lowerQuery = query.toLowerCase()
+    return allItems.filter(item => {
+        return item.name.toLowerCase().includes(lowerQuery) ||
+               item.comment.toLowerCase().includes(lowerQuery)
+    })
+}
+```
+
+### Integration Flow
+
+1. User opens launcher
+2. If empty trigger: Your items appear alongside apps
+3. If custom trigger: User types trigger (e.g., `#`)
+4. Launcher calls `getItems(query)` on your plugin
+5. Your items displayed with your plugin's category
+6. User selects item and presses Enter
+7. Launcher calls `executeItem(item)` on your plugin
+
+### Best Practices
+
+1. **Unique Triggers**: Choose non-conflicting trigger strings
+2. **Fast Response**: Return results quickly from `getItems()`
+3. **Clear Names**: Use descriptive item names and comments
+4. **Error Handling**: Gracefully handle failures in `executeItem()`
+5. **Cleanup**: Destroy temporary objects after use
+6. **Empty Trigger Support**: Consider if your plugin benefits from always being visible
+
+### Example Plugin
+
+See `PLUGINS/LauncherExample/` for a complete working example demonstrating:
+- Trigger configuration (including empty trigger mode)
+- Multiple action types (toast, copy, script)
+- Search/filtering implementation
+- Settings integration
+- Proper error handling
