Forgot to respond to this part . . .  The body-to-body direction
vector should definitely be added. The spin vector . . . maybe. I find
it useful, but it maybe somewhat confusing to people, since it's
usually coincident with the z-axis of the body frame.

The menu for the body-to-body direction vector is only shown for
objects that aren't directly orbiting a star. Otherwise, it's the same
as the sun direction vector. Opinions on whether or not this is a good
idea?

The body-to-body direction arrow is a reference mark where some useful
extra functionality could be made available through script. In the UI,
the second body is always the frame center, but it would be useful to
be able to set it to something else in a script.
