Is there a way to display the latitude and longitude for planets and moons. If not could this be added. Ideally selectable (toggle) by right mouse click.
I will be adding a feature to display lines of latitude and longitude. Whether it makes it into the next version or the one after depends on how fast I can get through the bugs that are left to fix.
On the Windows version, try the "Goto Object" option from the Navigation menu. It lets you specify a target object, as well as latitude, longitude, and altitude.
