Feature request? selective orbits...

[ogg]

Hi guys. How does Celestia recognise moons, planets, asteroids/comets and spacecraft as moons, planets etc etc for the purposes of drawing orbits for the planets and moons but not the others? Would it be possible to selectively display orbits for different classes of object? Could it be done on an individual basis, eg a 'show orbit' right-click option in the GUI to fix the orbit of a particular object as 'on'. (example use: to allow you to compare the orbits of several comets at once, with or without planetary and/or moon orbits)
cheers - PS, love the multiscreen option in 1.3!!!
