Should have been done ages ago.
Not only it allows you to use wires for decorative purposes or to make them match the environment. It can also be used for marking wires when building complex devices.
On another front, the new feature is moving forward. Actually, I added colored wires to help me with something to do with it. I also managed to let it be affected by electricity, in addition to crafting.
Will tell you more later.
Btw. I haven’t yet found any sensible service that allows people to vote on pictures. We need one to do the screenshots poll. If you have any suggestions, please let me know.
