Hello,
I am about to write an introduction into electronics for kids. This
introduction will also contain small circuits to experiment with. For
building the circuits, I'd use a breadboard like this one:

To draw the schematics, I'd
Hmmm... perhaps you could make the breadboard with vias, lock them,
connect them on the solder side, and change the via color to match
the far side color?
The breadboard wouldn't be an element itself, but a template .pcb
file.

So why not use pads instead of vias? Pads on solder side would represent
the holes in the breadboard and special footprints with pads
Vias connect the two sides, so you can test for connectivity. That's
all I was thinking. If connectivity can be done another way, then you
have other options.
