Hey i love your art software alot could you add a feature where you can change the color of the canvas in the settings and add an icon to the art software itself and the option to make custom brushes soon and dockers and animation features?
i'm glad you loved it :)
About the future features you ask:
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 :)
