Circuit boards should count output pins, not output connections

Circuit boards were expected to function as identical to the circuits that they contain, but because circuit boards try to create one pin for each external connection, rather than each connected external pin, this is not quite true.
Most importantly, the limit of 7 connections instead of 7 pins is very restrictive. It's very common to have a single output pin outputting to 4 or more places. No circuit board will allow two such instances at once.
But also, it's not possible to distinguish between a group of pins which share an output and other pins which output a completely different kind of signal. For the user of a circuit board, this makes things unclear.

Yeah, when we have an output connected to multiple external chips we always have to add a '+' chip outside of the circuit board to split the signal. When you have complex circuits with many outputs you'll lose a lot of ink by adding these normally unneeded '+' chips.
It would also be cool to have the same thing for the inputs. I often have to connect a single input to multiple chips inside my circuit board. For the moment we either have to use multiple pins of the board connected to the same input signal or to also add a '+' splitter (inside of the board this time)

Julien France: Multiple inputs would be much harder to handle due to race conditions, but all chips allow multiple connections to output pins, it would be nice if the Circuit boards did the same.

If you Edit the Circuit board, you can see where the pins connect internally.
