my problems with the inventory are a bit different,
what i really really need is that, when the inventory is open, pressing F1 F2 F3 F4 you change the inventory to that character inventory, not that i need to use the mouse to the small arrow to change!
and another great improvement (maybe alternative to the aforementioned one) is that, having picked up an object, the press of F1 F2 etc send that item to that character, the right click and select the right person is a nightmare!
