As it is now, ships in the battle viewer move around as though they are on rails, and very rarely face their opponents (let alone face them when firing!) This can sometimes look really wierd, especially when most ships very obviously have their weaponry pointing forward.
I propose that the movement system should take into account inertia and thrust, with ships rotating independently of their current heading. Ships would then attempt to face their current target, aligning most of their weaponry in the correct direction.
This would be more pronounced for larger hulls. Big battleships and dreadnaughts wouldn't quickly close with their targets due to low acceleration, meaning that they'd sit at the edges of a fight and pound the crap out of everything from a distance as you might expect.
I think this would make battles a lot more interesting to watch, since they would behave closer to what would be expected of the "real life" counterparts.
