 - **Launch Teams click semantics** — left-click = launch / surface / restore;
   right-click = stop. Was previously ambushing operators with a stop-Teams
   dialog when Teams was hidden via the eye-toggle.
+- **Auto-record on meeting start** preference. Recording auto-flips ON when
+  Teams transitions into a call (UIA Leave button appears) and OFF when
+  the call ends — completes the unattended-show story.
+- **MUTED / CAM OFF pills** in the IN-CALL bar via UIA — local-user state
+  visible at a glance without restoring Teams.
+- **Phase E.4 (experimental) — Teams window embedding via SetParent.**
+  Reparents Teams' main window into a TeamsISO-owned host so Teams appears
+  visually INSIDE TeamsISO. WebView2 in modern Teams may render glitches
+  after reparent; if so operator unticks and falls back to auto-hide mode.
+  Live in `TeamsEmbedWindow` + `TeamsLauncher.EmbedTeamsInto` / `RestoreEmbed`.
+- **Loudest sort mode** + **active speaker row highlight** (3px cyan left
+  border) — operators react to who's talking without scanning every VU bar.
+- **NumPad 1-9 hotkeys** toggle Nth visible participant's ISO. Generic
+  `RelayCommand<T>` added so XAML CommandParameter strings convert cleanly.
+- **Snapshot frame to PNG** (per-participant via right-click + bulk header
+  action). Saves under `%USERPROFILE%\Pictures\TeamsISO\`.
+- **Recording drive free space** in the footer (`· 245 GB free`). Coral
+  tint below 10GB; existing DiskSpaceWatcher still auto-disables at 1GB.
+- **Recording elapsed duration** in the footer next to the count
+  (`REC 3 · 12:45`).
+- **Quick-join meeting URL** + **IN-CALL pill with meeting title** for the
+  headless workflow — paste link, click Join, see what meeting you're in.
