We all had this problem - we need to get a specific value for our circuit so it works as intended.

So you place down a constant, set your value and connect it where you need it to be.

But that's slow and takes up space!

Wouldn't you like to just set the value right in the gate or building? That would sure save a lot of time! 

Introducing virtual connections: no more constants - just set the value right in the configuring interface and that's it!

Virtual connections can have any connection type that fit the input's demands!

To create virtual connection, aim at the building, hold G, and select "Configure object". Then go to "Wires" and click "Create virtual connection" on the input that you want

Note that not every type supports virtual connections yet!

Here's how it looks in the game:
