I certainly like it, the item tracker would definitely be useful. I would say that I would replace the up / down weapon swap with 'up' to use a heavy ammo synthesis, 'down' to use a special ammo synthesis. I would also argue that being able to cycle all your different weapons goes against their 3 weapon design choice. The choice of your 3 weapons would become less meaningful if you could swap them out that quickly, changing them out should be risky for the player in my opinion.
