On the note of the keys, how about a keychain too, and most definately get rid of used keys/quest items. I love the tidy button. Dungeon Siege has a tidy button, of course I always run into inventory space problems when the items are assigned blocks (ie. axes are 2x3, bows 2x8, potions 1, etc.). I also like the Dungeon Seige idea of a pack mule though. It's nice when you are encumbered to quickly put those heavy items that are worth big bucks on someone else's shoulders.
