Something came to my mind while I was playing SP. When I was flying around the mod-made systems like Utopia, X-3043 and Sol, I noticed that there's no mooring fixtures or any sort of station that can receive Capital class ships. I dont know if thats intentional, still worked on, or perhaps impossible. I'm a fan of FL CF Battleships, so I'm hoping for the developers to make the bases and planets accessible to battleships too. So my suggestion is:
1) Develop some mooring fixtures on the new CF systems or,
2) Make an "Ambassador" fighter class ship that represents the battleship for landing on planet or bases without mooring fixtures
I hope the devs considers it
