I've used a mac occasionally and there are really only two features I miss from the trackpad level: - Add a finger to click. This is very useful to be able to click without stopping dragging your finger. - The acceleration curve for pointing feels more natural. This was surprising to me because I use Linux primarily but I feel like I hit targets slightly more on MacOS.

With libinput I have found that multi-touch gestures work really well we are just missing application support. It seems that this project doesn't aim to work on applications at all so for me it seems like they are barking up the wrong tree. For example I would love to have Firefox wired up to linux three-finger swipe gestures for forward/back (and I bind down -> Scroll To Top and up -> Close tab).
