It would be interesting to configure what can be crossed or not. It could also be interesting to have a configuration that enables crossing in items of different colors, this to maintain some of the complexity of vanilla.

For example:
A red wire can only cross wires of other colors. It cannot create electronic devices. In this case, if a wire crosses a red wire, it will follow the game pattern and join together, changing what it is... Now wires of other colors will overlap.
