Slides are a great tool to help illustrate what the speaker is talking about.
When you share slides, they are likely to become near useless, as you cannot provide what you said while showing them. Or the order in which you explained them.

What could be great is to be able to attach a talk, splitted in paragraphs, and going from a paragraph to another would trigger an action in this fashion : jumpToFragment(X).OnPage(Y).

This way, anyone would be able to read a standalone comprehensive presentation, and not just slides anymore.

This is the closest thing I could find but isn't enouph in my opinion:

Your tool is already awesome by the way,
Cheers,
