I bought Dell XPS 13 9360 this week. I'm not happy about the status quo of current touch pad in Wayland. I want 3-finger drag so that I can free my another hand like my Mac. I did my research on libinput and Wayland. The developers does not seem to be motivated to do anything about it in near future (see my comment https://bugzilla.gnome.org/show_bug.cgi?id=768421#c5).

I don't have time to figure all the things out and patch it. So I suggest we use bounty source to motivate them: https://www.bountysource.com/issues/38423871-support-three-finger-drag

Disclaimer: I'm not the developer. I just want this feature badly in Gnome Fedora.
