I would like to see the hotbars sorted by type (one for spells, one for scrolls, etc). Really, though, we don’t need everything available down there. If they would just auto organize our backpacks we can just put the most used stuff on the action bar and just activate the rest from a neatly organized inventory.
There is an auto sort feature in the inventory, but it's not in a very obvious spot. At the top of the inventory screen and a bit on the right, there's a button that let's you autosort by type, weight, or a couple other options. It will be nice if they make it a little more obvious though.
Just realized you probably meant a backpack you'd pickup and not your full on inventory. I already typed it out though so I'll leave the tip in case anyone was unaware. That would be a really cool feature.
