Basic programmable hotkeys would be nice for inventory functions like split item, drop item, add to wares, send to camp, examine etc.
Can be kind of time consuming having to right click then go down the list for each and every item instead of just mousing over the items and hitting a key to do the function quickly and efficiently. Making those functions customizable in the hotkeys would be useful too so the player can choose how they want to manage those functions.
I'm sure it's been mentioned before, but maybe not. Just figured I'd add my 2 coins.
