I've been trying to figure this out for a while but I want to be able to separate items from the main inventory windows so it doesn't end up getting full. For example books are heavily used in my game but I don't want them stored with more useful items like potions and stuff and I don't want them all to become Key Items neither, I want to make something like a book bag, Ore Bag, Fish Box, ect to deal with the separate inventories so that the player can spend less time scrolling threw an inventory screen that can easily have 100+ items. I'm sure this is possible, but I'm not exactly sure how.
