Spacecraft orbits do not appear to go in front of planets.
Any way of turning off moon orbits, just to avoid screen clutter ?
Small and trivial aesthetic problem
The problem is that Celestia renders the 2d orbit lines before the 3d planets, so they always appear behind them. To fix it, you would have to render the orbits in at least two halves, one before the planets were plotted and the other afterwards.
Of course, I'm not sure how easy that would be to implement...
