When expressing circuit diagrams, it is common to fold multiple individual wires into a single, thicker "wire". See for example: https://eater.net/schematics/6502.png, examining the various address and data buses.

When building actual circuits in CRUMB, it would be nice for cleanliness purposes to use some metaphor for a ribbon cable: a single thicker wire which could be routed to and fro throughout the circuit, but finally opened up at either end to expose its numbered or coloured ends, to be connected to ICs.
