Layout Modes

Two engines, chosen per workspace

OmniWM offers two layout engines, and each workspace picks its own. Switch the active workspace’s layout with Toggle Workspace Layout (Option + Shift + L by default) or configure layouts per workspace in the GUI settings.

Niri (orientation-aware scrolling containers)

On monitors using horizontal orientation, windows form vertical columns that scroll left and right; in vertical orientation, they form horizontal rows that scroll up and down. Each container can hold multiple windows or be “tabbed” — multiple windows with one visible at a time.

Hyprland Dwindle (BSP)

A binary space partition layout that recursively divides screen space. Each new window splits the space in half, and a tile can group multiple windows as tabs. Best for traditional tiling with predictable layouts.

Floating windows

Windows can also float above the tiled layout in either engine:

Toggle Focused Window Floating (unassigned by default) floats or re-tiles the focused window.
App Rules can force matching windows to float — or to tile — instead of the automatic classification.
Raise All Floating Windows (Option + Shift + R) brings every floating window to the front, and Rescue Off-Screen Floating Windows (unassigned) recovers strays.
Scratchpads hold floating windows in ten toggleable slots.

Fullscreen: OmniWM vs native

Toggle Fullscreen (Option + Return) is OmniWM’s own fullscreen: the focused window fills the monitor while staying on its workspace, under OmniWM’s management. Press it again to drop back into the layout.
Toggle Native Fullscreen (unassigned by default) uses macOS’s built-in fullscreen, which moves the window into its own native fullscreen Space outside the tiled layout.
