I often need a blob that is smaller than 1 point. The ability to go smaller would be wonderful!

I use it a lot to "paint" wispy caligraphic lines.

I often use the bursh with equal width and height because any other setting slows me down as I change the angle I "paint in". If there was a way to interact without going back to the dialogue box it would be more efficient. It is slow and "clunky" otherwise.
