Now that we have some nifty fuel use going on for in-system flight, it finally becomes worthwhile to fly the most fuel-efficient route to the destination.
To do that we need a visual representation of the player's orbital tradjectory, as well as the tradjectrories of any targets which we wish to rendezvous with (Planets and stars are already visualised)

Here's some mspaint art ;)
First this is what the autopilot does:

And this is what would be seen if the player was to perform a Hohmann transfer

The blue line would be the tradjectory that the player's ship will take.
Basically this is just a way of visualising where the player is and where they will be, as you are always moving in space from one perspective or another, so its good to see where you will end up.
