Gestures work properly on any ROM. I made a tread just because i saw a lot of people saying the same "gestures don't.work....." crap. They work fine as long as you install Magisk and Nav Remover Module.Sadly nope, gestures only works with Xiaomi's launcher (either poco launcher if you are using an stable official rom or milauncher if you are using anything else).
I wish we have the possibility to AT LEAST use custom icon packs (like with poco launcher) on the mi launcher, but meh, we'll have to live with this. =/
