Some UI improvements are very much needed to the tile editor.
* The rotation adjusters are terrible as you have to move your mouse in a tiny tiny circle. Often you slip over into one of the other circles and rotation madness is a fact... Some way of using the keyboard here would be good.
* The XYZ-sliders move items in too large steps and requires very sensitive mouse movements. Again, being able to use arrow keys or something would be nice.
* No exact positions. Perhaps we need a box with a numerical value as well to make sure things have the same size or are at the same place.
* Load screen. I'd rather have a normal Windows interface here that lets me sort tiles by date etc. Imagine having several hundreds of tiles stored when you can only view 6 at a time...
