Two windows, one column
Stack a window into the column on its left or right, reorder it inside the stack, change its height, and pop it back out on either side.
Both directions
Stack into the left or the right column, and pop out to the left or the right.
Heights that fit
Make a stacked window taller or shorter by a preset or by a step, or share the height equally again.
Reorder in place
Move a window up or down inside its stack.
Scrolling Windows is optional. It stays off until you turn it on. While it's on, window snapping and automatic window snapshots pause, and restoring a workspace turns it off; the strip saves its own session instead.

Scrolling Windows
Every window becomes a column on a strip that runs past the edges of the screen, and new windows slide in without squeezing the rest.
Try it live ›Column widths
Cycle a column through preset widths, nudge it wider or narrower, make it full width or center it on screen.
Try it live ›Tabbed columns
Turn a stack into tabs when each window deserves the full height. A clickable tab bar shows what's in the column.
Try it live ›Grid tiling
Switch a display from the strip to a grid, and every window you open divides the screen into smaller pieces.
Try it live ›Strip overview
Hold ⌃⌥ to see the whole strip. Click a column to jump there, or drag it to reorder the strip.
Try it live ›Scrolling on several displays
In Scrolling Windows, each display keeps its own strip or grid. Send windows to the next display, and switch Scrolling Windows off for any display.
