macOS: double-clicking the split divider should equalize splits #8357

^{Originally posted by pavelxdd July 25, 2025}

Issue Description

I was going to make a Feature Request about this issue, but searching through the repo found (#4354) so I suppose this feature does already exist, but it doesn't work on my macOS (15.5). The only way to equalize splits, is find this option in Cmd-Shift-P popup menu.

Expected Behavior

Double clicking on a divider should equalize splits.

Actual Behavior

Double clicking on a divider has no effect.

Reproduction Steps

1. Open ghostty
2. Press Cmd-D to create a split
3. Resize split by mouse/touchpad
4. Double click on a divider and nothing happens.
