Or a "junk" section similar to some other popular RPGs. You can move the item you don't want there and it won't clutter your inventory. Then, when you get to a merchant, you can just "sell all junk."
I'd also like it if non-usable quest items went into a "quest" item section. I don't want to carry an Elder Scroll, Dwemer lexicon and three unusual gems everywhere for the rest of the game after they've become useless. I'm actually hoping a "remove quest item tag" mod comes out soon so I can just dump them period.
I cut my RPG teeth on Morrowind. I know not to lose [censored].
