Might sound weird or niche, but I think it'd be a good feature to be able to store things other than money in wallets. Like a folded letter or note. I don't know if business cards are able to be stored, since it's a thing I still gotta foig. What I'm suggesting is a pretty minor thing at first but could have some great RP potential for all sorts of characters. Terrorists planting bait wallets at the lev, corporate characters exchanging business cards like in the American Psycho, sending a cryptic message to a dip, and so on.
