 Open one or more local files with **⌘O**, drag them onto the video, or use Finder's **Open With**. A selection replaces the session's queue and plays in natural filename order (for example, episode 2 before episode 10). Open YouTube with **⇧⌘O** or drop a video link. Media starts automatically and resumes its saved position; finished videos restart from the beginning. Live and audio-only media do not save progress.
 
-The start screen uses a two-pane layout: Terebi's identity and version on the left; **Open…**, **Open URL…**, and the six most recently played local files or YouTube videos on the right. Shortcut hints follow your configured bindings. **Open URL…** reveals a focused inline YouTube field. When the most recent item has saved progress, it appears once as a **Resume** row with its saved timestamp. Recent titles and ordering survive relaunches; failed opens are not added. Resolved streams are excluded because reopening them requires a fresh external handoff. The action pane scrolls in small windows, and drag-and-drop remains available.
+The start screen uses a fixed 640 × 400-point two-pane window: Terebi's identity and version on the left; **Open…**, **Open URL…**, and the six most recently played local files or YouTube videos on the right. Opening media restores normal resizing; closing media returns to the fixed start size. Shortcut hints follow your configured bindings. **Open URL…** reveals a focused inline YouTube field.
