With all the stuff there is to loot and collect in the game it's nice to be able to use; pouches, bags, backpacks, chests, etc. to organize your inventory.
It would be awesome if you could take, for example, a generic backpack or pouch, and rename it to something like; potions, throwables, scrolls, jewelry, etc. (using same UI as used to create custom map markers)
then you could add a rule for what type of loot would automatically store to said container, like; potions, throwables, scrolls, jewelry, etc.
(maybe once a container has been named and given rules, it could have the same orange outline around it that the alchemy bag, and camp supplies pack have, to signify that is a special auto-sort container)
Also adding a quiver that auto-sorts/stashes all the different types of arrows into it, to the inventory, would be awesome.
This would keep your inventory more tidy, and help you organize all the different types of items you have, without having to spend as much time sorting through everything.
