Tracer or target-painting weapons... tracers do minimal or no damage, but if a tracer hits, all fire from the source ship to the target ship gets a bonus to hit for a short period of time as specified in the tracer weapon's component entry (maybe +10 to hit for 2 seconds). If a neural combat net or similar component is installed on the firing ship, the bonus applies to ALL similarly equipped ships firing on the target. Tracers could be any type of weapon, from direct fire to seeker to point defense to even ramming warhead. Since they would typically do little or no direct damage, they could even be area of effect or arc weapons without causing too much game imbalance
Skirmish mode - much requested in Starfury, but maybe now that you've got the combat engine worked out, you could include a mode where a player chooses ships/planets/units/etc. of any tech level and chooses an enemy fleet and then runs a battle a la Starfleet Command. Perhaps even a multiplayer Online skirmish mode, and/or multiplayer Online tactical combat?
