This app is great ! I already tried to make some sprites for my project. There's one suggestion i'd like to add. Could you make Layers tab be in portrait mode, to be on the left or right window anchor? Because it's a bit crowded when you got 5 layers you can only see one at all times.Or at least drag-and-drop option to rearrange Editor, Layers, ColorPicker, Tools :D Good luck with your further development team :D
