Simple suggestion. Automatic doors for bases and capital ships, but they link together to make one big door. you can use T to activate it manually, but otherwise it only opens if a POWERED small vessel core is within X range and not docked to a base or capital ship.
When one door gets triggered, either manually or automatically, all the doors that share a plane also open, folding open like collapsible shutters and allowing for large sealed hangers.
