They get lost along all the files. Also would be nice if I could save the name to something. It currently saves to result [some number].
Also great work, I was looking for a tool like this, I have a lot of sprites that needed something eye catching (I'm updating a sci-fi space adventure, needed a way to show damage on ships) and this can quickly add that without me manually creating the spritesheets or asking my programmer to spend time creating these effects in game.
I look forward to any updates and am a big fan of all your tools, keep it up, I'm sure you'll have a full suite soon. :)
