I'm glad to see this tool is still begin worked on. (even if slowly) Would the tool Tiled be of any inspiration?

I've been using it myself for my Game Maker Studio projects and it's pretty decent. There could be a few more features of course. I like how they included isometric as well as the normal 1:1 tile grid.

Something I'd love to see is a hex tile grid. Maybe animated tiles and of course the ever popular auto-tiles.

Would you consider making Tile Studio export to various formats? XML, match other popular tools (like Tiled), JSON and others?
