I would like to see a full set of clothing and armor slots. I long for the days of Morrowind levels of control when I could wear a full set of armor over my extravagant clothing, with an enchanted skirt, robes and lest not forget the pauldrons.
EDIT
Also on the concept of weight to money, Super Hydlide added weight to coins, the more you carried the slower you walked. You could find a money changer to lighten that load up with notes.
