Pen support
It would be cool if there was support for wacom tablets/pens. For example, mapping buttons on the pen to the eraser. Xournal++ currently supports this as a source of inspiration:

(oh, unrelated but I just created an AUR package for pointless, might be cool to put in the readme: https://aur.archlinux.org/packages/pointless)
For this there might need to be a global settings menu
I'll implement somewhere in the far future.
Regarding your AUR, please use v1.6.0 :) I will update my README with your link.
oh yea, it already used 1.6.0 but I apparently forgot to update the version of the package itself. nice!
@jonay2000 thank you, I just merged a PR that has added your link to the README.
@jonay2000 would you mind updating AUR with 1.7.0? This version will be the final one for a long time, because I won't have time for at least 2 months to develop on this project.
Will do
