Keyboard first
⌃⌥ with the arrows moves focus, add ⇧ to move windows, and W S make columns wider or narrower. Every shortcut can be changed, and they work on any keyboard layout.
See how it works
Every window is a column. The strip carries on past the edges of the screen.
Drag the strip sideways, or swipe it with two fingers, the way a three-finger swipe scrolls it on your Mac.
Windows in a row
They open beside you
A new window joins the strip next to the one you're using, at the width you like. Nothing else moves out of the way or shrinks.
The strip runs on
Columns carry on past the edges of the screen. Move along with a shortcut, a swipe or the scroll wheel, and the strip glides there.
You stay in the flow
Focus follows you down the strip, and the timeline shows where you are. No overlapping windows to dig through.
Swipe and scroll
A three-finger swipe follows your fingers and settles on a column. Hold ⌃⌥ and scroll with two fingers or a mouse wheel to do the same.
Drag to arrange
Drag a window between two others and they slide apart for it. Drop it on a column to stack them, or hold it at the screen's edge to reach columns off screen.
The timeline
Hold ⌃⌥ to see the whole strip at the bottom of the screen. Tap ⌃⌥ to keep it open and rearrange windows right there.
Remembers your layout
Your columns, widths and stacks come back after a restart, on every desktop and for every set of displays. Plug your laptop back in and windows return to the monitor they were on.
Rules per app
Let an app float, start its windows full width, or open them at the end of the strip. Fixed-size windows and dialogs float by themselves.
At home on your Mac
