A searchbar for items would be SO USEFUL. Type "pyramid" in one character and it'll tell you who has the pyramids and let you use or select them. Also agree that an item name list might be more useful at times than an icon inventory. Switching

A shared inventory option would be nice too. At least a way to display all characters' items at once, if still slightly separated.

An auto-send feature, pleaaaaseee. Send arrows to your ranger no matter who picks them up, automatically distribute healing potions and food equally (or slightly more to one character), etc.

Shared lucky charm effect, too. Hate being like, "Oh crap I looted with the wrong character >.<" (Especially since I buffed lucky charm in my game). That should not be a concern.

Group looting of containers. Isn't that on the controller UI? Nothing like looting 5 crates with 1 item in one of them.

Just throw durability in the garbage unless it can be interesting. If you had skills that broke your weapon on using it or something, and you had to have lots of weapons and maybe spend time in combat repairing, MAYBE that would be an interesting use of durability, but right now durability just doesn't add anything to the game. MAYBE if there was a higher blacksmithing requirement to repair higher level items, it'd incentive investing in blacksmithing on a main character instead of a mule, or you'd have a gold sink on repair, but there's better ways to balance the economy.

Larian, don't let competitive questing get in the way of a much improved inventory system.
