Linux distros are barely just getting their feet wet in the tablet/mobile world. I would say "barely just getting their toe wet" :)
Getting back to the point. I loved the way iPad was integrated with the stylus (Apple Pencil). My use case for a tablet back then was to write/draw stuff I did "remotely" and export all my, let's call it drawings, to mac and work on that. Today's example. I was planning a garden layout. It took me way too much time to get the stylus working the way I expected and when it did I had more issues trying to export the drawings to a usable format* I would be better off with a good old pen and paper.

I've been using GrapheneOS for over a year. I cannot complain about it, it works as advertised and it does it the best way possible. However, here's the list of things I find annoying/missing. Keep in mind, this is a subjective list.
