Que-ing up ships.. build order.

Sorry, but you can't. It will build the same ship over and over till you tell it differently. You can use the Ship Build Manager to change every world building one ship type to another ship type.

I suggest that you figure out what ships you want the most of, and have some of you planets build them non-stop. I don't bother to build more than a handful of different types of ships at any given time. If I design something new, its ussually to be a better version of another design.

I tend to mass produce medium hulls on most of my worlds, while I leave my other planets with the task of building some troop transports and constructors. I also tend to make some of my worlds to be factory worlds. With lots of factories, and a power plant, I can ussually build my best ships in the fraction of the time it would take to build them on other worlds.
