It's been a while since I've been on the forums, but I still use ArtRage all the time. Thought I'd throw in a request that I *thought* I had seen before, but 2.5 still doesn't have the feature where I can find it.
I really want a way to export one or all of the layers to PNG files. Yes, I know that this means only the color and alpha, and not the paint/wet/media information, but that's okay. ArtRage is my pencil board, and then I want to take a stack of penciled layers and work in other art tools with those sketch elements.
By the way, ArtRage has saved my floor from a metric ton of eraser crumbs!
