Comment 1 for bug 1071457

Additional explanation. When suggesting this feature I am considering use cases where one want to see the lunar motion around the earth or the Jovian moons around. For those two one would always center the central body but be interested in the orbiting satellites and that of course would make seeing their orbits very nice. When centering on the child instead one does get the desired orbit line but then the parent moves around while the child stays still, rather confusing to explain orbital motion in that view.
