Not sure I'd it's been mentioned in my long hiatus from the forums, but for the campaign I would love to see an option for refit/rebuilding preexisting ships, some of the AI designs are not awful and just require a basic rework where as others need a full redesign, yes we can just build new ships and copy and paste old designs, you have no recourse to improve designs in a time frame that a new class cannot react to (worse for larger classes obviously)
