This video demonstrates the following features:

00:00 Starts with the “Locked Sidebery” layout, where vertical tabs are locked in the expanded state.
00:05 Uses Firefox's built-in dark theme.
00:10 Switches to a third-party theme. Sidebery's background color automatically adapts to the theme's accent color.
00:13 The bookmarks toolbar expands on hover. Background images from the theme align seamlessly without breaking at the navigation bar.
00:17 Unlocks vertical tabs using the toolbar button. Sidebery now automatically collapses and expands on hover.
00:24 With Mica enabled and the system theme active, the browser background appears translucent with a soft frosted effect.
00:26 When vertical tabs or Sidebery are expanded, their backgrounds also display the Mica backdrop.
00:29 When Sidebery is active, native vertical tabs are automatically hidden to avoid redundant UI. Sidebar toolbuttons collapse into a small colored stripe at the top of Sidebery and expand on hover. When expanded, the sidebar toolbuttons also display the Mica backdrop.
00:34 When vertical tabs are collapsed, the layout remains clean and centered, with extra UI elements removed.
00:37 Pinned tabs stay in place during expand and collapse. When vertical tabs expand, all tabs remain in the same vertical position, so there's no need to reposition your cursor.
00:50 Vertical tabs can be fully hidden with a toolbar button. They reappear when the mouse touches the screen edge.
01:00 All browser UI elements can be hidden with a toolbar button. Moving the mouse to the screen edge reveals them. In this state, only the web page is visible. When maximized, this layout feels like fullscreen but still allows access to the Windows taskbar.
01:08 With Mica or custom wallpapers enabled, the visual effect changes depending on the background used.
01:38 The navigation bar can also be fully hidden and revealed on edge hover. This is not shown in the video, but this setup can be combined with “Lock Sidebery” to create a Zen-like layout.
01:41 When the number of tab panels in Sidebery exceeds one row, they automatically collapse.
