On the wishlist of features, I know it's quite impossible to have it (because it would be too difficult/complicate/too heavy on the code), but it would be interesting if you can had a "tactical mode" to the combat, in which the player can manually control his ships on the battlefield, deciding their path and their targets and so on.
This could be fun, as it would be add a new layer of strategy to the battle (for example, if there are asteroids on the battlefield, you can move the ship behind them, effectively hiding them form the enemy - unless they have powerful sensor arrays - so you can perform ambushes, of focusing fire on specific ships to cripple the enemy), insted of simply watching the ships flying ad shooting at each other.
Yeah, something like that would be fantastic, but, it's really hard to get the AI to use the tactical features with anything like the skill and nuances a human player will. Which can turn it into a cheesy exploit, instead of a cool feature.
Brad and many others @ Stardock have said that there will never be direct tactical control during battles. for tactical battles look for Sins2 which will be announced sometime later this year....
