Hey, thanks for the comment and showing interest! I've recently resumed work on the project and yes, I am planning a some new features! Some of what I plan to add include:
Axial tilts
Rings
A tour of the Sol System with information on each of the major planets and moons
Camera maneuverability
UI, shader and lighting improvements
Theres are all things I planned for an update in the near future, afterwards, I intend to go back and rework a lot of the existing structure, optimizations and such, and when I do that, I think it would be a good point to include things like naming and asteroid belts
