[Feature Request] Vertical layout option for Mac (move bottom panel to the right, like Windows v1.28)

Feature Request: Vertical layout option for Mac (like Windows version)

The Windows version of Fork has a vertical layout option that moves the bottom panel (Commit / Changes / File Tree) to the right side of the commit list. This is very useful on widescreen monitors, as it gives more vertical space for reading diffs.

Could this layout option be brought to the Mac version as well?
