Hello there and thanks for this great piece of software! It would be great if we would have an absolute tracking mode and "hold left click" for mouse input, so that one could turn a phone or tablet into a graphic tablet (like a wacom board). There are a few apps that do that on Windows, but no solution for linux, the input mode of kdeconnect being the closest thing to it.

I would like to +1 this request as well. It would be great to be able to do some free-hand drawing (even if not touch-sensitive), for example to put a signature on a digital document, by simply using my iPad and Apple Pencil, using KDE Connect to transfer the mouse strokes to my Linux laptop. Thanks a ton for fighting the Apple ecosystem to bring KDE Connect to iOS. This is one of the best apps in the KDE Ecosystem.
