This is one of my favorite 4x games (sorry to qualify it, but it doesn't come close to being one of my favorite games, although it's not any fault with the game, most- if not all- of my favorites are RPGs, like Baldur's Gate and Planescape Torment).
That said, there are a few things that can be made better, particularly in the combat viewer. Currently, all you do is watch your ships fight. I would actually love for you to be able to command your ships in battle. Right now, there's little point to researching or using components that increase your range, outside of getting in a few "long-range" shots. Nice, but your ships still close with the enemy, even if you out-range them. Being able to actually command your ships would negate that moronic tactical decision.
Second, and this might already be part of it, although right now it's pointless, do rear-facing weapons work? That would open up even more tactical choices. Say, using your rear facing weapons to annihilate the enemy while "retreating- i.e., keeping your ships out of range by running away."
Third, to negate that second point, if a ship does use that tactic, being able to command in battle would allow you to retreat if your enemy tries that tactic. That would actually make the ship tactical maneuverability components worth using as well. Currently, I don't see a point to them.
