Some windows float
Take a window out of the strip with ⌃⌥T and it floats above the columns; press it again and it tiles back where it was.
Float and tile
One shortcut takes a window out of the strip and puts it back.
App rules
Float an app's windows, or choose the column they open in. Rules apply to new windows.
Your session comes first
Windows the strip already saved come back where they were, whatever the rules say.
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 ›Stacks
Stack a window into the column on its left or right, reorder it, change its height, and pop it back out on either side.
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.
