Thanks Daza for the suggestions, and lectronice for the response!
As lectronice described, some of these can currently be achieved through scripting. I would like to revisit these at some point because I agree that they could open up some cool options for puzzle-type games! It's funny, because I originally planned for RPG in a Box to primarily for creating RPGs, but it has somewhat evolved to be more open for other genres like adventure. That is a good thing, though, and I hope to incorporate the features like you've mentioned in a more user-friendly way later on.
