We had similar in the ORRR2 mod for LoG1. It was just for potions, and weapon set swapping.
I've no idea why it didn't get put into ORRR3 for LoG2—and didn't know it wasn't until I checked for it today.

(But it's best if you complete the official game first, in order to appreciate what was added to the game by the mod.)
