That looks promising. I would love gestures on Zorin, specially Macbook like gestures.
I happened to see in a The Road to Zorin 16 post that one of the features of Zorin 16 is multitouch gestures. I would be curious to know how they implement it.
Multi-touch trackpad gestures for quicker navigation around the desktop. 4 finger swipe up/down to switch between workspaces and a 3 finger pinch to open the activities overview
There is also this project by Bill Harding that is trying to accomplish something similar: Get touchpads on Linux like on Macbook. I have been following it for a while and they seem to be doing a lot of progress.
I would just like to link it here so that DEVs or anyone not aware of it can have a look:
