Once your empire grows to the point that you are managing multiple fleets, which are possibly fighting simultaneously but at great distances from each other, it can be rather difficult to keep track of what is happening.
It would be really great if the player could get voice updates from the fleets. They don't need to be complex, and they don't even need to be voice-acted. Just some audio update that gives us the fleet number and current combat status would be awesome and very helpful.
"This is first fleet, the enemy is retreating."
"Second fleet, here, the enemy has the upper-hand."
"This third fleet, we are vastly outnumbered."
When there is a lot going on, this would be a great way to give the player a heads-up that a decision needs to be made quickly.
