+## Monitoring
+
+Use `playwright-cli show` to open a visual dashboard that lets you see and control all running
+browser sessions. This is useful when your coding agents are running browser automation in the
+background and you want to observe their progress or step in to help.

+
+The dashboard opens a window with two views:
+
+- **Session grid** — shows all active sessions grouped by workspace, each with a live screencast
+  preview, session name, current URL, and page title. Click any session to zoom in.
+- **Session detail** — shows a live view of the selected session with a tab bar, navigation
+  controls (back, forward, reload, address bar), and full remote control. Click into the viewport
+  to take over mouse and keyboard input; press Escape to release.
+
+From the grid you can also close running sessions or delete data for inactive ones.
