Just some feature requests:
A drawing tool that feels more like "a drawing tool"... The blob tool is a GREAT start, but not quite there. I would love a tool that feels more like a traditional drawing Pen or pencil. The shape tools and rubber band tools are great for precise shapes, but as a traditional artist, sometimes I just want to "draw" and feel like I am drawing.
In line with the above, it would be nice to have some steady stroke settings available as well.
FIx the Kuler panel! I do realize one can still "simply click and go to the kuler website", but that is not even remotely as useful as being able to have it at your finger tips as one works.
Just my two cents.
