It would be great if I could create a TEST app and then when the bugs are worked out of new fields or features update an existing app with record information from ongoing projects instead of having to create a whole new app/fields then go and redo all the work in the original app that I wanted to update. The reason to not just update the intended app experimentally from the beginning is the possibility of disrupting operations or worse loosing already collected data. The test app allows for data importing and then testing to see if the changes would in fact cause data loss.
