I created a textbook supplement for Electric Circuits. Am I missing anything critical?
I would probably add source shifting to the list of useful stuff. It's not hard to understand, and can help to convert sources to the right type using source transformations.

I also don't understand why RLCM-circuits are discussed under DC Circuits. In DC an inductor can be considered a short-circuit, and a capacitor an open circuit. The chapter seems to describe transient or large-signal behavior.

Also, in opamp circuits I always force my students to first check for negative or positive feedback using what I call the "arrow method" - I don't know if it has an original name. Only if there is negative feedback, and \$A\to \infty\$, you can say that \$v_p = v_n\$. If the feedback is positive, then the opamp should be treated as a comparator, and \$v_p \neq v_n\$.
