Ripspace allows you to organise your ships into named fleets. You can then filter the list of visible ships to only contain those in a certain fleet.
This is all handled through the fleet menu item. The window below allows you to create and organise your fleets of ships.
Races who come to dominate the heavens find this useful.
You must create fleets using the fleet maintenance menu item, you can allocate ships to fleets using the fleet dropdown on the ship display at the left side of the screeen.
