I would like to suggest following the system default theme that is available from Android 10 (API level 29):
Relative motion support
I forked this (and the driver) and added an option to support relative input for touch input. This will open up a lot of options for gesture-based input such as two-finger scrolling or two/three fingers for right/middle click which I plan to implement soon. Feel free to give it a try and let me know if you’re interested in merging it at some point.
Thanks! I’m very happy that the project is used by other people and at some time, when the code base has proven stability, I will be happy to merge other people’s additions.
