I know this feature has been removed due to the lasers being pretty now and because everyone should have them enabled at all times.
First let me say this: they look pretty, you're right on that one.
The problem i have is that even they look good, i don't like it that they are going all over the place, making looking at my base a mess.
To make them look neat, i need to create "bridges" to go around corners and such which causes the energy loss to add up more then i really want it to.
Could you please re-add the option to turn off the rendering of the lasers? Or at least the option so they are only visible when holding the wrench?

The Energy Loss doesn't get higher when more lasers connect two machines. It's always the same percentage from machine A to machine B, no matter how many lasers are inbetween.
So no problem making corners ;)

Okay, perfect, my bad ;)
Now you gave me a pretty grat idea how to integrate them in my base and make it all look awesome :D
