The sockets has one connecting point,
The problem in this case is when I want to wiring an extra pin with another part of the circuit, that become very confuse, but there is not a bus with double pin side.
Another problem is when for example, you have been working wiring an element with different pins and suddenly you realize that it needs more pins, when they are added at beginning of the element it become problematic. Half of times need to be rewired all the circuit again to fit it in the new pin number, so...
Could be possible to add an option asking where to add the new pin when resizing in the properties?
