Agree with the Export request. :)
As a 3D artist (I can do all the things and stuff), being able to export my "FlowScape Doodles" (because that's what they are; 3D painting and rendering while sipping on some good whisky or rum, listening to some ambient-chill music and just getting lost in the creative process...with no real ultimate goal in mind). So put me down for an Export feature!
