Hi plazma,
Good tips!
1. Works with things like Net Labels, Ports, and Pins as you showed.
2. Great tip, always connect a port to a wire in the circuit so it knows what it's connected to, before worrying about what it looks like. Depending on what you connect it to, it may change its look, for example, to show direction for input or output.
Best regards,
