Much as I love the area loot feature, it can be a bit annoying that it also picks up a bunch of junk guns and other items that I don't want weighing me down. Sure, I could go through and pick each item up one by one, but that's slow and tedious.
Instead, I'd love something of a counter to the lock feature, with which you could instead block an item from ever being picked up in the first place. You'd still have to go through and manually block each item and variant, but at least you'd only have to do it once.
Not sure how easy that would be to implement, or how many people would actually find it useful, but I'm tired of having to scrap all these dang pipe guns when all I really want is ammo. Heck, I'd settle for 'take all' only applying to whatever category is open.
