Premise: Much like the "send to camp" option when picking up loot, there is a "sell immediately" option. Sending stuff to camp, then going to camp and picking it all up, and then running it to a vendor is a chore and frankly not fun. Maybe you can only sell common items so you can't accidentally sell rare magic items.
I watched a stream of "Solasta" and thought the idea of the Scavengers Guild was a super streamlined and novel idea of dealing with junk & encumbrance. I don't want that mechanic ripped off, but I would love something similar.
