Wow Tiled who? ;) the addition of the brush and prefab tool is killer. Would it someday be possible to load a pre-made png to auto-create prefabs? Example, if I made a tilesheet with everything sorted together as I'd like, and spaced them out on a transparent canvas? I'd consider this a low-priority request though, I have had no real trouble creating my own!
I continue to deeply appreciate your work on this project!
