Launch a rocket via the circuit network... and it might even go where you want it to.
Providing the player with new tools or adjusting the game interface, without fundamentally changing gameplay.
Transportation of the player, be it vehicles or teleporters.
Augmented or new ways of transporting materials - belts, inserters, pipes!
Entities which interact with the circuit network.
i'd like to leave the signal as "auto" and just name the targets whatever with a way to exclude some of them,
Example: using a combinator to send a " Launch Rocket" signal with the value of -1 to the hub of a ship i want to be excluded.
