Just an idea.
During and after fights (sometimes) reinforcement is needed. An additional feature of a fleet could be, that it automatically starts to create the reinforcement, if the player toggles it active for it. This could be as simple as that, or could get an own management window, where the player can set up his settings for the reinforcement, like what factories should be picked to create the reinforcement or resource conditions to automatically create reinforcement.
As managing reinforcement is a skill on its own, this could be an option that can be disabled for a match.
As I sayed, this is just an idea and I have no problem if it isn’t implemented.
