I'd be interested in finding out what the level of interest in such a feature would be.
Only as a option and not the default one. In GCIII late game you could have many fleets and no way of knowing when you were moving the last one, you could then miss some other move you needed to make.
Another suggestion an option for NO enemies in your home sector. I mean all other races are enemies as none are ever my friends when I play. As it stands, I just started a game on largest galaxy map with TWO opponents and one was within 30 or so tiles of my home world in the middle of my home sector.
For me this is a game killer, it makes the game absolutely unplayable for me. AN option would be to immediately release the map editor so like in GCIII I could place the alien scum as far away as map limitations allow.
