I've never found a program this epic, nor one that would save so much time. Back in my Game Maker 6 days, I always hated compiling sprites, because of ripping, saving, joining, alligning, etc....
But now all of that is fixed with one innovative tool! Of course, this is very useful for other engines as well, but it popped out to me, because of my GM frustrations.
I'm downloading this as we speak, also.
