Sure, there are actions packed with the plugin. But they are only :
Save Checkpoint
Resume from Checkpoint
Check For Resume Data
Save Game
Get number of saved games
Get save game Info
load saved game
delete saved game
set player name
These 2 actions don't save a scene. They save one single gameObject. And they let you load that saved gameObject into any other scene. In effect, it does the same job as saving something to a prefab, only that it works outside of the editor too.
The unity serializer is big, and there are lots of juicy functions. Since I couldn't find additional actions I thought they could be of use to anyone else wanting to do this too
