+
+Shows the current Mangowm tiling layout and keymode on your bar. Click to open a picker and switch layouts instantly.

+
+## Plugin
+
+| Field | Value |
+| --- | --- |
+| ID | `x0d7x/mangowm-status` |
+| Entries | Bar widget: `status`; panel: `layout-picker` |
+
+## Requirements
+
+- Noctalia v5
+- [`mmsg`](https://github.com/mangowm/mango) — Mangowm's IPC CLI tool (must be on `PATH`)
+
+## Usage
+
+### Bar widget
+
+Add the **Mangowm Status** widget from the Add-widget picker in your bar settings, or configure it by hand with:
+
+```toml
+[widget.mangowm-status]
+type = "x0d7x/mangowm-status:status"
+```
+
+The widget displays the current layout's icon and letter code. When the active keymode is not `default`, the keymode name is shown beside the layout code.
+
+- **Left-click** the widget → opens the **Layout Picker** panel. Click any layout to switch immediately.
+- **Horizontal scroll** over the widget → cycles through the core layouts (T → S → G → …).
+
+### Layout picker panel
+
+Open with:
+
+```sh
+noctalia msg panel-toggle x0d7x/mangowm-status:layout-picker
+```
+
+A scrollable list of all 14 supported layouts. The current layout is highlighted. Click any other layout to switch — the panel closes automatically.
+
+## Settings
+
+| Setting | Type | Default | Description |
+| --- | --- | --- | --- |
+| Hide on default | `bool` | `false` | Hide the widget when keymode is `default` |
+| Show text | `bool` | `true` | Show the keymode name beside the layout glyph |
+| Notify on change | `bool` | `true` | Show a notification when the keymode changes |
+
+## IPC
+
+Control the widget from the terminal:
+
+```sh
+# Refresh layout data
+noctalia msg plugin x0d7x/mangowm-status:status focused refresh
+
+# Get current status (logged as JSON)
+noctalia msg plugin x0d7x/mangowm-status:status focused get-status
+
+# Set layout by code (T, S, G, M, K, CT, RT, DW, F, VS, VT, VG, VK, VF)
+noctalia msg plugin x0d7x/mangowm-status:status focused set-layout S
+```
+
+## Layout Codes
+
+| Code | Layout | Icon |
+|------|--------|------|
+| T | Tile | columns |
+| S | Scroller | menu |
+| G | Grid | dashboard |
+| M | Monocle | window |
+| K | Deck | cards |
+| CT | Center Tile | layout |
+| RT | Right Tile | columns |
+| DW | Dwindle | columns |
+| F | Fair | layout |
+| VS | Vertical Scroller | menu |
+| VT | Vertical Tile | columns |
+| VG | Vertical Grid | dashboard |
+| VK | Vertical Deck | cards |
+| VF | Vertical Fair | layout |
+
+## Notes
+
+- This plugin spawns `mmsg` subprocesses to query and change the compositor state. `mmsg` must be installed and on `PATH`.
+- Layout changes use `mmsg dispatch setlayout,<name>`.
+- The widget keeps two long-running `mmsg watch` streams (keymode + all-tags) for live updates, with a 1-second polling fallback.
+- The panel entry fetches tag data on open and does not keep a persistent connection.
