lunar nodes

Could you add the ability to view the lunar nodes?

We had this request numerous times. To repeat this answer: our lunar positions are not computed as longitude along an orbit which intersects the ecliptic at the nodes, but directly as XYZ coordinates, so we have no actual geometry to display. You can display the current nodes when observing from the geocenter with orbit drawing activated. We are open for suggestions regarding the actual algorithm that should not include computing a series of lunar positions and should work with all ephemeris models in use, with just a single state vector (time, 3D position, 3D velocity) as input.
