A couple nitpicky UI things

I could not, for the life of me, figure out how to swap items. In Arc you can drag an item from one container and drop it onto an item in your backpack and the two items will swap places. Was this even possible in Marathon? If so, I couldn't figure out how to do it. Without that ability, it makes it super tedious to loot if your backpack is already full, so I'm hoping I just missed it. Also, in Arc there's a big "drag loot to here" box to drop stuff on the ground that isn't in Marathon (I think). Basically moving stuff around and manipulating inventory was tedious.
