Compare test and live settings

As we’ve moved into Live mode several hiccups have happened because I failed to setup Live mode properly.

It would have been helpful to me if I had way to compare my Live settings to my Test Settings. Is there a way to download all the settings for Live or for Test. Just comparing the JSON would highlight problems.

Which settings should be same and which different will vary from customer to customer, and also as new features as added, so nothing too specific is required.
