First of all, great game, enjoy the ship editor and i think it´s a very nice idear and lookin forward to make my first crew training missions when it´s implemented.
But i wanted to drop my another 2 cents to the idear. How about you make a primary powerline and a primary cooling line. Like you got it in sci-fi series or novels. Call it what you want, the mainenergy grid, main eps conduit, primary powerline etc... and the same for the cooling system, like primary cooling grid or so.
The power and cooling lines are a pretty awsome idear but at the moment its a real pain to design ships in a way where you need to connect each single generator to certain systems and to do the same with the cooling lines. And from a engeneering aspect it´s logical to create a main powerline from where all secondary powerlines spread out to the systems in the ship. It gives a ship also a very tricky weak point. Land a hit at the main powerline and then prey that the designer thought about to create a backup grid that can handle at least minimum shipfunctions.
