I'm not sure this has been suggested, but I think it would be nice to have a safety deposit box for items that we want to keep, but that we don't want clogging up our inventory.

Say you have an item you like and for some reason you want to keep it. Maybe saving it until it's worth more later. But at the same time all it's doing is clogging your inventory. Perhaps it's not that bad when you only have one or two of those items, but when you have tons of them it can make navigating your inventory a bit more difficult.

Just an idea I thought I'd throw out there.
