Ey man. I know you probably won't see this, as you may be busy with other things, but I just wanted to let you know that you have something pretty damn special here. It's a very niche tool that only a few people would get use out of, but those few people are very glad you put the effort into making somethin' like this, like myself. I just wanted to commend your work with this project, it's probably crazy how much work you put into these sprite overlays. I hope you plan on making this program as fleshed out and useful as you can!
