MichelBy the skin of my teeth, and JUST for the end of #marchintosh, I'm releasing libmui which is a Linux UI interface library heavily inspired by MacOS classic (and GS/OS!). https://github.com/buserror/libmui
Adam Nelson@buserror I really like the underlying header-only C graphics libraries. Render directly to an RGBA surface with no dependencies whatsoever, then just use OpenGL or whatever else you have to blit it to the screen. Inefficient, perhaps, but still more efficient than IMGUI, and it's the most portable API possible!
