I would suggest a switchable view in the inventory screen (I), more precisely the right side. At the moment there is a simple list wich isn’t sorted by alphabetical order but the vague order of the bodypart layers. If one wears a lot of items and odds, it ends in a annoying searching for a special item.
So in my humble opinion i would be nice to have the possibilitie to switch the right side of the inventory screen from the actual view into the encumberance panel of the layered clothing view. That view is for some needs in a good sorting, even it has doubbled entries in it.
