[REQUEST] Mark the keys that have already been used

theoricus

I don't know if anyone mentioned this earlier, but personally I would really enjoy the feature of automatic marking of used keys after you open the doors (at least in key's description, preferably in inventory window). It would be useful especially for new players, and would facilitate cleaning up inventory.

Just add the keyring for the mod and the problem is also solved, and it's much easier

Keyring seems better choice And IRL it's easy to make/buy
