The most change I want back is the shop's lower side. It's been annoying me since the beginning, because it seems so awkwardly spaced. I usually get along with these stuff but I.. I can't with the new one. Here's a little photoshop I did, just notice the bottom side as I've changed it back to a similar format as the old HUD. I know the new HUD is for some new stuff but I really can't get along with the new shop interface at the bottom.
