I really like this idea, but one of the big "improvements" for me in the scavanging system (given that I didn't play New Vegas, which I believe implemented some of this) is that it's no longer just about weight to value ratio, and it's also about rare components (screws, gears, etc.) for weapon mods. For this to be useful to me, it would need a customizable "hit list" of crafting components as well.
Am I the only person who collects lots of stuff early in a quest, runs out of room when I find better stuff, then drops a bunch of it in a locker/cigarette machine/corpse near the front door in the hopes that I'll stumble across it later (current return rate = 0)?
