When mousing over, say, Medium Hulls in the tech tree, I don't see any evidence of the several pre-made ship designs that become available after research of this technology is complete. How am I supposed to figure out what is needed to unlock, say, a Ranger? Or a Phoenix? I can appreciate that designing the ships myself is much more flexible than using the pre-made designs, but for the first few games, I at least want to look at those designs...
