It would be nice if you could have a box you could check to "lock" certain loot that way you could sell all the junk at once and still keep the rarer ones you want to keep.
I did buy 1 and seen that if you put a loot in a display case at your house and sell the rest it will still be there on display. However it would be nice to just keep certain ones in your inventory with out having to buy a bunch of loot display boxes.
