 Use the **Queue** icon immediately left of the compact-mode button in the playback controls, or **View → Show Queue**, to show the editable sidebar.

 Resizing with the queue open preserves the video's aspect ratio while keeping the sidebar at a fixed width; closing the queue retains ordinary aspect-locked video resizing.
 
-While the sidebar is open, its persistent top header holds the pin, Cast and settings controls without a surrounding glass container, with matching top and right button insets; these and the bottom queue controls do not fade with the video controls.

+While the sidebar is open, its persistent top-right overlay holds the pin, Cast and settings controls above the list without a surrounding glass container, with matching top and right button insets; these and the bottom queue controls do not fade with the video controls. The native layout check verifies that all three header glyphs actually render.

 Playback advances automatically and stops at the end, without wrapping. **Previous Queue Item** and **Next Queue Item** are available in the sidebar and Playback menu and are disabled at their respective ends. Reordering or removing another item does not interrupt playback; removing the current item plays its next neighbor, or stops if there is none. A playback error stays on that item rather than skipping it.
