 A lightweight widget plugin that shows Tailscale connectivity status on the Dank Bar with quick controls for toggling connection, switching exit nodes, and copying peer addresses.

 ## Features
 
 - **Status icon** in the bar — `vpn_key` when connected, `vpn_key_off` when disconnected
 - **Right-click** to toggle Tailscale on/off
 - **Left-click** to open a popout showing:
-  - Your current Tailscale IP
+  - Your current Tailscale IP (when connected)
   - Active exit node (with clear button)
-  - Peer list with hostnames and IPs
+  - Peer list with hostnames and IPs (when connected)
+  - A clear "Not connected" empty state when disconnected (no stale peer list)
 - **Click-to-copy** any hostname or IP to clipboard
 - **Exit node selection** — click `↗` on any exit-node-capable peer to route through it
 - **On-demand status** — polls Tailscale for ground truth on load, explicit actions, and post-mutation verification (defensive poll-act-poll for toggles; no always-on timer)
+- **Single-flight actions** — concurrent status/toggle/exit/copy chains are rejected while an operation is in flight
 - **Toast notifications** for all errors

 - Uses `Proc` singleton (from `qs.Common`) for all external `tailscale` commands (one-shot stdout capture + auto cleanup).
 - Fully I18n-ready via `I18n.tr(...)` (source keys in American English only today; see `tailscalectl/i18n/` for scaffolding).
 - Follows current `dms-plugin-dev` + DMS 1.4 plugin best practices (capabilities, requires, no raw Process for one-shots, etc.).
-- Toggle uses intentional defensive poll-act-poll (see code comments).
+- Toggle uses intentional defensive poll-act-poll; a failed status poll aborts the pending toggle (does not invent `up`/`down`).
+- When `BackendState` is not `Running`, peer list / exit node / self IP are cleared so the UI never shows a stale connected-looking peer list.
+- Status row uses `RowLayout` with a real `Layout.fillWidth` spacer (not a no-op on plain `Row`).
+- Peer `ListView` uses `Flickable.StopAtBounds` (no desktop rubber-band overshoot).
