Love this tool!
I know this has been asked before, but it would be really fantastic to get an "export at current resolution" option or something, just to save the extra step from having to go into Photoshop/etc and resize all the output!
Also, it would be awesome to have a "tiled view" to see what the image looks like tiled, to see how it looks repeating and so on :)
Just some suggestions! I love it as-is as well. Thanks for this tool!
