Each moment in the Story Builder plugin can save the state of the document at that time. By turning on Auto Save in the plugin, moving things around when you are on various moments will update the state of that moment automatically.
Note, this is only autosaving in the memory of the plugin. To save the CODAP document with the plugin that has various moments stored as part of the plugin you still need to save it to google drive or to your local machine.
Thanks! When you are finished creating a presentation using Story Builder, do you recommend turning the autosave off so that a user can interact with the various moments without being asked if they want to save/discard any changes they made?
Actually, I think it is the opposite. If you share a presentation you probably want autosave on so that it doesn’t ask if they want to save changes before moving to the next moment.
