Here's my suggestion on how you could improve the inventory system in Day Z. With such a powerful inventory management that the game has, this new layout could reduce the amount of scrolling needed. In other words, it'd be easier to go quick in-and-out of inventory. As for the pants, perhaps you could even move that inventory next to the shirt inventory (see arrow), if both inventories have a maximum of 3x2 slots. People are smart, they'll quickly figure out which inventory corresponds to which clothing type anyways, because of how the various inventories become available and visible as you get new gear. Also, I've removed the name of the inventory parents because showing names is redundant, imo, when you should just be able to mouse-over to see the name. Notice also how I've reduced the "Player" frame width, because I feel there's a lot of wasted space in the pane.
