Nice write-up by Carlos, long time contributor, about the future of advanced tablet pad support in #GIMP: https://blogs.gnome.org/carlosg/2023/06/16/getting-the-best-of-tablet-pads/
Mostly #Wayland-only (Linux) for now, though #GTK will hopefully get backends for Windows and macOS eventually!
The code is still in review, but not doubt it will be in GIMP by the 3.0 release. Very exciting!
