Thanks, quite the useful simulator; I hadn't found that page yet. Additional considerations for circuit simulators:

What does the simulator say about signal delay and/or propagation in electronic circuits and their fields? How long does it take for a lightbulb to turn on after a switch is thrown, given the length of the circuit and the real distance between points in it?

(I learned this gap in our understanding of electron behavior from this experiment, which had never been done FWIU: "How Electricity Actually Works" (2022) https://www.youtube.com/watch?v=oI_X2cMHNe0 )

Electrons (and photons and phonons and other fields of particles) are more complex than that though.
