Window

Window puts the focused window’s column controls and workspaces on the Island. Open it from the Launcher destination or a compositor keybind:

kanade window toggle

Target	Effect
Consume right	Joins a neighboring window into the column
Expel bottom (niri)	Expels the column’s bottom tile, not necessarily the focused window; disabled with one tile
Join / split (Umbriel)	Uses Umbriel’s consume-or-expel action, available even with one tile
Maximize, Float	Toggles the compositor’s corresponding state
⅓, ½, ⅔	Sets a proportional column width
Preset	Cycles the compositor’s configured widths
Workspace pill	Moves the window to that workspace on its output

Arrows and Tab move the ring; Enter or Space presses the selected control. Escape collapses the Island. The header keeps the remembered focused window available while the Island has the keyboard. State follows compositor events without polling.

With no focused window available, the Surface says so. The window-surface Module gates the Surface; turn it off and its verb and Launcher destination cannot open it.
