Yeah, a warning message as it saves over each/any files is probably a good idea. I'll look into implementing that. Truth be told, a warning box like that should be easy if I was using Forms and all the other built-in GUI stuff in C#, but since the tool is written on top of my game engine, which uses SDL and OpenGL for everything, it's more of a challenge. But I'm sure I can get something to work. Thanks again for all your feedback and suggestions! I haven't forgotten your other ideas, they're all on the queue to work on when I get a chance. :)
