How to split a pane by dropping on an edge
Published by BetterStage · Instructions for our macOS app; detailed feature reference is linked below.
Steps
- 1
Turn TabStack on for the monitor.
- 2
Drag a window’s title bar into a left, right, top, or bottom edge zone of the target pane until the Split overlay appears. The tab strip is not a split target. Set the edge-zone size in Settings > Window Modes > TabStack > Split drop zone size (0–40%); 0% disables edge splitting.
- 3
Release to create a new pane on that edge. This is pane-edge drop, not macOS edge-drag snap.
