What I want is a way to design just hulls with jewelry. Then every game have just the hulls to choose from. Maybe I'm doing something wrong but when I design a whole ship maybe 1% of the time will I use that ship again in another game. When I need a ship odds are I won't have the excact same techs as before. It's annoying me to have 50 different designs pop up every game that I don't, and probably never will want.
I went to the directory (forget wich one now) to deleat ships and it didn't look obvious as what to delete. They were named what looked like pre designed ships.
