1) the canvas code allows change canvas color, set transparent and even change the transparent checkerboard colors, it's only left a GUI code to adjust that.
2) about the icon the program is still very early and the gimp pepper logo is temporal (probably is copyrighted by some image research lab)
3) if you look at my Mastodon there is a post of a mockup about how brush presets would look. Right now I'm focusing more in engine stuff before continue with GUI, this order would guarantee high quality code
4) frame by frame animation features are for a very future 2.x, the core architecture is designed to embrace such future features :)
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
Thank you for testing!!!, i builded it with arch linux, so i will update demo binary building on debian to be more universal
Regarding building manually from sources if you used Nim package from debian it is also outdated, I will update README.md adding how to install latest Nim
