Not sure if this has been suggested before but I tend to build my ships in modular sections and upgrade as I go. I'm still running my original Iron ship except now it is Trinium/Xanion Hybrid and a lot bigger but it would be nice to be able to split the hull and move the engineering section farther aft and add a hanger section or another cargo section. Without having to select the engineering section, copy to clipboard, save clipboard, delete section, add new sections, upload to clipboard, and paste the engineering section back on.
What I do works, don't get me wrong, but it is cumbersome.
