It might be nice to have a "Turbo" or "Max Speed" button on the time controls, opposite of the "Stop Time" button. From playing the game, I recall plenty of times when I've started/equipped/configured everything I needed to in my bases and I want to simply increase the time rate until something happens.
For the air combat, perhaps this button could change into a "disengage" button that zooms everything back out to the normal view, so the player could attend to some other matter (for example, going to a base menu screen, loading/saving a game, etc).
