One small request for ship designer options. Please allow components/modules to be mounted inside the ship chassis, as opposed to only being able to be mounted externally.
Although I really don't care for Star Trek, I do like the visual idea of the Borg ships as just huge squares in space. When I first started playing GC2 I was disappointed to learn that the "square" hulls still required components to be mounted on the outside.
(this also solves the ship designer issue of figuring out where to place an "ugly" module, if it detracts from someone's ability to get that final pizzaz into their dream boat)...
When I bothered about ship appearance, I usually solved this in GCII by rotating the component and playing with the scale slider to make the part invisible (or mostly so). Which I admit isn't perfect.
I certainly wouldn't mind a setting that made the functional components of a ship (or selected such components) invisible, but it wasn't impossible to work around in the GCII designer, so as long as that remains true I won't complain.
