Glad I could help! I've done my best to make everything as simple and easy-to-understand as possible, but between the big sweeping GML changes since I first created this project butchering some of the organizational aspects, and an RPG being pretty dang complex to begin with, things can get a bit overwhelming.
(Btw, if you haven't already, you might want to check out the old comments as well, I've answered a lot of programming questions for misc common features over the years and if you have a future question it might've already been answered in there)
