An idea thought about the other day. Is a ability to save and make copies(circuit blueprints) of players own custom Integrated circuits.
Idea is that when you want to save a placed down already made custom circuit, that you can pick-up?, place in some kind of circuit copy bench, and make blueprint copy of the circuit. This copy then could be saved client side, and used in single player, on other servers, or even shared with other players.
This could prove to be a great feature to have for those who wish to repeat their custom circuit(s) on multiple setups. Or to allow players to use their saved custom circuits for the future as needed.

Good idea, could be useful

Added the Circuit Database for this purpose
