Fleet maneuver is too stupid

In combat I often have the situation that my fleet moves towards the enemy ships. When my strategy is not to come too close to the opponent, I have to turn my fleet by 180° and move to the oposite direction. This works fine with the fleet leader, but not with the other fleet members. The more ships I have in a fleet, the larger is the curve that the other members make for the 180° maneuver. That's really bothersome as then they easily come into the range of the enemy's weappons range and will be detroyed.

The stupid behaviour of the fleet members is not necessary, as we are in a 3-D world! The fleet members could also turn 180° at their current location as the leader does. OK, the orientation of the members has been changed (left side is now right one), but who cares? The formations are usually symetrical, so it does not really makes a big difference whether a ship is on the right or left side of the leader.
