Years ago, you had a Spaceship mode that presented galaxies volumetrically so that a pilot could leave the Milky Way then cruize across its outskirts, all while spotting where the Sun was positioned. One could then point at another galaxy, see its distance, and watch that distance diminish as the 3D generated image got larger and larger. The ability to fly out to other 3D generated galaxies based on their known types was a phenomenal experience for everyone. If one traveled far enough, there was a place where the total known universe could be viewed. I realize it was not technically correct, but it was the most beautiful feature for children and adults who want to grasp the grandeur and scale of the universe.
The current Spaceship mode falls far short of that version from years ago. There are no 3D galaxies that you can visit. For example, if you point to M31, it doesn't show you the remaining distance. It just vanishes at some point along the way.
I recently upgraded just for this feature as it was advertised as improved, but it's really not useful and still a far cry from the earlier versions. Maybe if the idea of providing what you had 10 years ago is not acceptable to your astronomer audience, you should consider a spaceship mode only Starry Night Traveller that recreates what you had and more. It was a joy and I'm sure would be hugely popular.
