@rahmanusta@markdalgleish What I'm planning to do for this use case is to implement an "export" plugin that exposes the deck as a public API. This is needed, for instance, to export the deck using deck2pdf in a portable way.
This plugin may register the deck on a collection attached to the bespoke object. Something like "bespoke.decks".
Btw, I made an adapter so that you can use the onstage plugin from dzslides to power a bespoke.js presentation. I still plan to make an official (or more official) presenter view, but for now this fills a void.
