What are your favorite tricks to control a fleet in OP?
Here is my basic approach to fleets in OP:
1) Build them according to SFB CnC, it usually works out for the best anyway.
2) Pick a formation for the situation and stick with it (we know that control is unreliable - but see number 11 for clarification).
2a) I tend to go with the line astern formation as a set it and forget it kind of thing - especially in terrain.
3) Do not change speed and direction too quickly or too often, you'll confuse the simple minded AI.
3a) Do not go to fast, pick speeds, accelerations and decelerations and rates of turn that all of the ships in your fleet are capable of (also to give the slow AI a chance to clue in...). Excess speed is the most common cause of AI falling from formation, keep it slow and calculated and they will stay close.
4) Stay in the flagship or carrier, don't jump around command if you can avoid it, this also confuses the simple AI.
5) Never let the AI control a carrier while it has fighters/PFs.
6) Strip your AI of shuttles to prevent their suicidal tendency to weasel at the drop of a hat.
7) Always set your AI ships to fire on your target and usually only on your command (they pick the worst times if left on their own).
8 ) Only set your AI ships to overload rarely, when you are sure the whole fleet will be going slow enough for 2 or 3 turns.
9) The AI 's respond well to well timed capture and tractor commands - use them.
9a) Abuse captured ships... don't try to keep them in formation as they are usually damaged, leave em behind, though ocassionally I have recycled marines from one captured ship to capture another.
10) Stay away from planets and map edges - AI are very scared of them, not quite as scared of asteroids.
10a) Mines are the enemy of your formation as the AI seem to fear them most, bear this in mind, and use it. (I've used drones or even my own ship to clear mines to maintain formation)
11) Be aware that the fleet formation control is relative to the first ship in the list, not the ship you are in, this can be confusing sometimes.
I may think of more to add later, feel free to add your own.
