I saw someone ask, what's your favorite developer tool to use when making builds?

We have a great tool where we call resource nodes, like cheat nodes, where we can have any resource come out of it at any rate or any volume.

And same thing with resource sinks.

And we have the same one for fluids as well.

And that is very handy for just getting your factories up and running real quick.

Would you mind spoiling just one tiny thing we haven't seen?
