While I like the annotations, I have to say they make it difficult to make out the original equation. It parses and highlights variables and gets in the way of seeing a cohesive whole equation.

I think an annotated version would be good as a supplement.

I'd prefer definitions of terms to appear when you hover the mouse over them. And the proofing software to enforce that all terms are thus defined. Somehow in 2021 at least, undefined terms were still slipping through the review process :-/
