I'm +1ing the bestiary idea.
Also the ability to see what statuses on you or enemies actually do would be useful.
The ability to see how many of the item you have in the shop.
Lastly making queued missions actually start after you complete the current one and increasing the amount of queue-able missions by one or 2 would help push the game back towards the "second screen game" status that the missions are currently leaning away from and that the first 2 planes suggest the game is going for.
