I really wish there was a storage item for locked room keys. I have keys all over the place and each kind takes up a whole slot.
There have been times when I did not realize I already had a key to a room and waited around for one to spawn.
It would be so nice to have a key ring that keys would go to when I found them and they would be easy to keep track of.
(This has nothing to do with the key ring that we use for keys to our friends' houses.)
