I previously made a small Mac window management utility called Gridly, which lets you arrange windows by swiping with two fingers across the title bar. In this 1.2.0 update, I added a feature I’ve wanted for a long time:
Once Gridly fills the remaining space with your most recently used windows, divider lines appear between the windows. Drag a vertical or horizontal line to resize the two adjacent windows at the same time; in a four-pane layout, grab the center point to move all four in their respective directions. Each window’s minimum size limits how far you can drag. The divider lines disappear after the next snap, pressing Esc to undo, or switching displays.
Try it free for 14 days, then buy it outright for $3.99. It stays in the menu bar and takes up about 3 MB. If you’re already using it, you can upgrade from the menu bar by selecting “Check for Updates.”
I’d love to hear what everyone thinks of dragging the center point in the four-pane layout and whether this interaction feels intuitive.
