These could be easily added, I never thought they’d be useful. Do you think they should be on the same window as the other options or brush controls should have their own floating window?
hmm, i'm not sure which would be better. maybe the seperate floatoing window because you could always just position it near the original if you prefer. is a vertical slider possible? my ipad app has a vertical sider that hugs the side of the screen and i find that very comfortable.
