Everyday I move between a Windows 11 laptop for work and a Mac laptop at home. What I kept missing on the Mac was the three-finger window switching from my work machine: window switching that is faster than alt+tab and single-hand, single-gesture.

ThreeSweep is that (but on MacOS and in terms of MissionControl), enabling the same one-handed single-gesture window switch: you use three fingers to swipe left (or right), MissionControl appears, and you drag those same three fingers over to the window you want, you release, and the window is focused.

It works via synthetic swipe up event (Mission Control trigger) + synthetic click (window selection trigger) to bridge trackpad events with the desired window selection behavior.
