It would also be nice to have a filextension that automatically opens with tilemancer...
Right now, when you open a saved file with tilemancer, it just shows black and the color picker, which by the way could be a bit bigger...
Another thing that is a bit annoying is the colorizer... if you have to add a color afterwards, you mess up all colours. It would be nice if the colors were mapped to a color in the pallette, and not just to a position on the color picker...
