I also think that it makes sense to:
- add ability to sort starships that you can recruit at starbases by, say, name or their points and/or cost.
- change the colour or the items that can be bought for your ship so that the cargohold (installed) items is easier to differentiate from the items for sale.
- add more pictures for different type of weapons so that they do not repeat (e.g. forward cannons and hypersonic nuke)
- add more planets with rings
- add more landable objects - dwarf planets, asteroids, comets
- autopilot (when setting course from, say, the log) shows to you the route first (better with a direction line) and then switches to actual nvaigation in the solar system
