Please add an option to retrofit ships in the shipyard, and the ability in the ship designer to group a class of ships together that I see happens with some of the core vessels. The little yellow arrow that can expand to show improved designs. (Not the one that separates missile, kinetic, beam, mission, etc but is underneath some individual ships).
When I design a class of ship I want be able to click on that ship class and have the varying options I have designed and have available open under neath it.
Right now I have so many ship classes and designs and configurations for different points in the game that it is a mess to look through and prior to starting a new game I open the file in my galciv folder that holds all my designs and delete them. It is so much easier just to do it all again as I go.
