I’m a power trackpad user while gestures works quite good but it’s very limited. I can not customize it to make it do stuff like so I use Touche for this but it would be great to have it by default. I really liked how WINDOWS implemented it. Couple of gestures I used to use are
3 finger swipe up/down to control volume +/-
3 finger tap to play/pause media
4 finger swipe up for taking screenshot and swipe down for system monitor ( Since there are just apps maybe make it launch applications on the gestures )
and brightness control, tab navigation and all that. Thank you.
