Unless I'm missing something, there's no way to see the current live configuration (for things likes Properties/Downloadables). That would be very useful to toggle between (live/preview) just like in the NoSQL page.
I guess for now the best approach is to use the multi-stage publishing guide approach of having 2+ games, so the second game would have all the live values?
It is possible to see the live configuration by previewing a snapshot.
You can preview a snapshot by selecting the magnifying glass in the snapshot bar.
Ah had not thought of that! Very good thanks!
