We haven’t decided if and in what form this should be added. However we did just release ZIP exports which makes it very easy to download all of the source files for a presentation (HTML/CSS/JS/images). Those files could then be added to an empty repository.

Still waiting for that feature, this is a huge limitation (plane, bad internet connections...).
The Dropbox backup is great, but not an alternative to offline editing.
The feature suggestion was created and marked as "Planned" 6 years ago.
Someone from the team could comment here on the ETA?
