Perfect! You even partially answered my last question, which is script order / stack. Thanks!
If I have two scripts that make calls to Window_Base, and they both define "draw_actor_hp", for example, does RGSS process it from the bottom up, with the last script taking priority or the first? I understand if the same method is called twice on the stack, it causes a "stack level too deep" error, but I'm not quite sure how multiple method definitions work together and how RGSS knows which definition to call.
