The trackpad is absolutely fantastic and despite not having used an Apple device for years, I found myself trying to use the three- and four-finger gestures. I did a bit of searching, and found a way to enable them: https://github.com/silexcorp/fusuma.
I’m running Linux Mint 20.2 and have set up the four-finger swipes for ctrl+alt+direction and the three-finger swipes (left and right only) for alt+direction. Apparently Fusuma can be set up for app-specific gestures with a plugin, and I feel I’ve barely scratched the surface here.
