I'd love to see more variety in the basic editing tools, so far we're limited to a resizable circular tool that acts much like the airbrush in paint packages, it would be great to see more shapes and control, i'd especially like a straight line tool for texture.
I was working away last night on my map and built a wall, I needed the mud texture on one side and the ground texture on the other, but it took me forever to get it right and even then there were odd spots where they bled together and I got tiny patches of green or the wrong texture on the wrong side.
