Ya, I know its hard and takes a lot of code but you can do it!
I look at a ship and i got some new stuff and i want to refit it. Eventually. My shipyard is always busy. So, I click the refit button and it says coin the work that is happening now. Well, I'm not entirely adverse to coining builds, but 9 days is a bit much. So I take a pass. How about an option to take this ship to design mode? So I can work out a build and refine it while my ship is refitting.
Guys, give us this.
