 Use the **Queue** icon immediately left of the compact-mode button in the playback controls, or **View → Show Queue**, to show the editable sidebar. The **+** button beside the queue count opens **Add to Queue…**; it and dropping files onto the sidebar append without replacing the queue or interrupting the current item. Drag rows to reorder, remove them with the minus button, and double-click a row to play it. The current item is marked; context menus also offer Play, Remove and Move Up/Down.
 
+The header's **+** uses the same bordered container and accent tint as the former **Add to Queue…** button.

 The navigation row has extra space above it. Queue rows use equal-width leading and remove-icon slots, with 8-point outer insets matching the gaps between icons and filenames and no additional horizontal scroll-content margin.
 
 In a normal window, showing the queue expands the window outward while preserving the video's size; hiding it removes that extra width. The sidebar meets the video directly, without a separate divider gap. The window shifts left when necessary near the screen's right edge. Fullscreen keeps its fixed bounds.
