I'm looking for a mod to reduce key clutter in inventory. There was a keyring mod for oblivion (couldn't find it on tesnexus, but it's on PES: http://planetelderscrolls.gamespy.com/View.php?view=Mods.Detail&id=7243) that would work. Even if, like that one, you can't see what keys you have it would be worth it to have them out of the way.
