Tabs are a special toolbar that provides quick access to the editor windows in your layout from the scene view. Tabs are meant to let you work contextually right from the scene with reduced visual obstruction.
By default, tabs are only shown when the scene view is maximized (full screen), but that can be changed from the Peek preferences to be either always or never displayed.
Tabs have two display modes: Popup and Pinned. You can switch between display modes by clicking the pin icon on the left of the tabs toolbar.
Popup tabs behave like the tabs in a web browser: only a single one of them can be open at once. They always appear next to the tabs toolbar and cannot be moved or resized. By default, they will take the size they had in your layout.
Pinned tabs behave like a floating workspace: you can open multiple of them at once and move or resize them around the screen. If you resize a pinned tab, that size will be remembered next time you open it in a popup.
Tabs appear in the same order as your current Unity layout, left to right, top to bottom.
However, you can override that order to maintain consistency across layouts.
By default, the order override is set to:
To customize it, go to Edit > Preferences > Ludiq > Peek > Tab Order. The dropdown list lets you pick any window type derived from EditorWindow.
Shortcut: Hold Alt+Shift+[0-9] to quickly toggle each tab.
Not all editor windows were created with tabbed display in mind. Some windows might exhibit unexpected behaviour when toggled as a tab, especially if coming from a third-party plugin.
Toolbars are contextual inspector shortcuts that allow you to view and edit a game object, component or asset without having to keep the inspector window open.
The Creator tool lets you quickly create new game objects directly from the scene view.
