I found a planet at one stage with a "destroy the transmitter" mission and "destroy 5 hives" mission. I drove around and through the planet and melted most of the surface but there was no transmitter.
It would be super useful if we could do this ship-wide as you build. Like turn on a mirror that lets you place/manipulate two objects at once. At least for me all of my ship designs so far have been symmetrical besides the keybindings, so this would have ~halved my building time.
