Show inventory while looting

I think it's pretty ridiculous that this isn't already in the game.  When I'm looting, obviously I want to know what's already in my inventory.  The only way to check while looting is to either have a full inventory and prompt an item to be swapped, or to completely exit the death box and open your inventory, both of which are very inconvenient.  It would be much easier if inventory was shown while you are looting instead, similar to the display that pops up when you prompt to swap an item except it's always visible.
