Was playing with list in the temples and had a few thoughts...
Would it be possible to list which items are in use? I kinda hate praying for something that someone else is actively using. If I'm lower on sacs, it's no big thing, it just tells me it's in use. When I'm higher, I may be taking it from someone who needs it.
I would imagine it's also possible to show who's got the item and how many sacs they have, though I don't know if that'd be a good idea or not.
