I know you are currently only doing this officially for Samsung tablets, but the Xiaomi Mi Pad 5 is a great tablet and it would be cool if I could take notes and change to eraser or switch color using the stylus 2 buttons. It should be possible since other apps can also utilize the button inputs. (Browser scrolls up or down for example)

I would definitely pay for this app if this feature was included! Thanks a lot for bringing this app to android, it means a lot!
