Itemized and flexible parameters to adjust the graphic interface of the HUD in-flight. It initially occurred to me that having the orbit lines be dimmable as opposed to just on/off would make the overall look of any type of extended flight (supercruise) more visually appealing, but upon examination, I realized that there are about 20 or so elements of the visual HUD overlay that could be customizable, and perhaps even augmented so that when you make hotkey type changes (like activating/deactivating orbit lines) the lines could fade in/out from their OFF State to their ON State (which would be an arbitrary visibility/brightness setting of your choice). Potentially you could even add visual heads up elemens like power DISTRO pips or target ident/shield status, even your own shields or your wingmate status, where they can benefit your flight.
