With regard to formations, changing direction in the real world is complex and takes time unless the formation is circular and direction driven by the guide unit. Well beyond my comprehension how this might be carried out in the app. I do know that in real life when the battlecruiser fleet changed course the screen had to be given at least 40 minutes notice. I wonder whether there might be some work around by making the current option to define station, permanent until changed relationship. Then use the ship identified as target as formation guide. Abit like using the target option, the app would need to modify speed, what it will mean though is that the Task Force could not move at anything like full speed and change direction. Well beyond my comprehension how this might be carried out in the app. Waht I do at the moment is ships in line ahead have the next in line as a target and I adjust the others speed and course. It is very much a hit or miss exercise.
