Re: break formation strategy
Click "Empire Status (the crown)" then "Strategies".
Find the strategy your fleet has (or the strategy you want to make break formation). Click it then on the right, you will see a button called "Formation". Click it to see where you can add all the ship(types) to break formation.
Hope this helps.
