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.Jens Claes commented
Or if we could download a full version of the slideshow. Now we can only have the slides but styles aren't copied.
And images still refer to the online webpage. It would be nice if there was a possibility to download the whole slideshow and just be able to run it offline. (so you have all files you need)
