Very useful things you need to know about. (Tips & Tricks)
Refit naval station weapons: I recommend beams or MIRV missiles - choose long range weapons. To refit a station go to the system that its at and open the fleets tab along the left - keep expanding the stations tab till you get to the station you want. Then you either left or right click the name to bring up the refit option.
Ship design all mount size to same weapon: Ever want all your small mounts to be PD weapons but tired of selecting all light mounts to swap'em to PD? Well, normally everyone left-clicks a turret and then left-clicks the weapon they want in it... BUT! If you RIGHT-CLICK the desired weapon, it'll make ALL turrets of that size into the weapon you right-clicked!
Splitting fleet for wider coverage in battle manager: You know in the battle manager when you drag a fleet out onto your colored "territories"? Well, it'll look like a bunch of small boxes on a grid that contain your ships - you can SEPERATE those boxes by clicking and dragging them away. This will allow you to have your fleets starting posistion much more to your liking. I.E. you may want to have your supply ships and command ship start much father back than your brawler ships.
