I guess ideally as app builders it would be great to be able to give test links out to potential customers where we could specify the number of days for a limited testing period of say 3,7 or 30 days etc. And this testing by the potential customers would be segregated to Test Data, without the app builder needing to switch the app to Test Data mode, because that will interfere with already existing customers. I think this would be a very very useful functionality.
