I Make mine improbable's words: "think it would be nice if the 'Shop' dialogues showed you how many instances of a given item you already had. In the case of units, it might be nice to see what is the maximum number you can deploy. This would save a lot of flipping between screens and fumbling around to decide on what you want to buy."
Those simple changes must be made to the game become more "player friendly".
