I don't know if it's possible because I'm not a developer.
I would find it nice that the slides are no longer in the html but apart, unitary and included (like a php include ()) dans le fichier html. This allows modifications in the slides by modifying only the file corresponding to the slide without modifying the html code and avoids errors. It also makes it smoother from my point of view
I think this makes reveal.js even more accessible to non-developers.
