It should not auto-reveal hidden items- you should have to search for them manually.
(...) it always makes me to smile, when I see bluesuits running to pick-up 1 bottle cap, because they just see "Bottle Caps" in description
I should add to the suggestion:This system should also allow us to pick up particular items from the stack. Too avoid having to scrounge through a stack of garbage to find the item we know is hidden underneath. It is NOTHING but a hassle for people with low carry weight to go through a pile of junk.
