Making ships, especially making starbases, rewuires [edit: requires] a lot of going back and forth between designs. It would sure be helpful if we could either:
A) have the default name of the edited ship be the original name (this happens already under some circumstances)
an edit button that would cause the default save name to be the same as the original game.
The ship designer already warns you if you are about to overwrite another design, so this would be a 'safe' modification.
