When I was working with maya using the hot menu, I was thinking that this could be useful for PA. When you hit the spacebar a menu will pop up. Whith this method options can be selected really fast. Options could be planet selection and other camera options like looking at the opposing site of the planet, space view, splitting the screen in multiple views and using one view. When selecting the opposite view in a secondary screen, this will be linked to your primary screen. When rotating your primary screen, the secondary screen will also rotate always giving you full view of a planet.
