Really snappy and pen support worked for me without a hitch through the itch installer (Bazzite/Fedora Silverblue with opentabletdriver installed in an arch box via a ujust script included in Bazzite). It's very clear there's still a lot to be implemented, some menu items simply don't do anything, but all the basics are there and feel great.

glad to hear you liked it and pen pressure worked on a non common setup ^^.
Right now i'm developing tiled layer system which is the biggest part of this project, after that and more gui toolkit rework i would be able to implement planned features more quickly
such layer system includes 25 blending modes, layer folders, layer masks and most important clipping group
