God almighty, how come I'm hearing about this for the first time??? this thing basically does everything GIMP does but better. I mean, node-based editor... are you kidding me, it's incredible!
after a couple of hours of playing, their node editor is still a bit raw (not blender level), but the foundation is very solid. i'm willing to back this project financially (after I use it for a week or so), and I strongly suggest you do too (if you find it similarly useful). we really need more projects like this so that (a) people stop using adobe, and (b) GIMP devs finally realise that to maintain the audience they actually have to do something.
