Please enable Beamer notes (including the "show only notes" beamer option) in article mode.

My use case is slides for mathematical lecture notes, with proofs to be done on the board. I'd like to have a cheat sheet with proof notes embedded in the LaTeX source, but the proof notes often don't fit on a single slide. I'd therefore like to be able to export them (and only them) in the article mode.
