Ok I'm not sure how easy this would be to add but I thought it'd be nice for there to be a few drawing applets to draw on and share art. The board would be divided up e.g: Beginners, Sketches, Advanced, Competitions etc. Then when you choose to draw you'll get a selection of applets e.g: Chibipaint, Shipainter, and canvas size, then the applet should launch. When you're done you can then publish the drawing to the board with a description.
The only downside is that inside of like your java properties on your computer you'd need to add the site to the exceptions list for the Java applets to run. Java's gotten pretty paranoid recently. And there would need to be mods to make sure there's no 3 minute drawing spam/only words and such. But it'd be a nice addition.
Ah and it won't work on Chrome >.<
I think I just need one thread to post all my suggestions |D
