So can you throw out things during missions to open boxes? I am liking it.

Yeah, go to items and if you don't have any potions/ether/etc. panels equipped it'll open directly to your bag where you can pick-and-choose what you want and what you don't. If you do have healing tablets on, just keep pressing X in items and it'll go to your bag after it highlights the last item.

Any item you toss out can be picked up again in case you make a mistake, but only while you're in the same mission. The bag clears after every mission, of course. You don't need to toss stuff unless you're out of room, really.
