When I am doing inter-planetary trasnfers I would love a 'Maneuver Planning Mode'. Make a key bindable to it. It would show only your node (you could not select anything else) and your target planet. I don't need my periapsis or the son's apoapsis. Just the basics. I have spent 10 mins having to zoom in to re-select my maneuver node - not to mention sometimes it would disappear!
