I think the Collect Audit Feature could be the best gift from the Development team in 2018. Working from Aggregate 1.7 and pulling data using Brifecase 1.13, the CSV file is very informative and resourceful. The file is able to let me identify questions field staff may have challenges or seem to respond to multiple times with one interviewee.
nice to hear that!
We are working on extending audit.csv file in order to log location coordinates in the background. If you are interested in this here is a link to the discussion: https://github.com/opendatakit/roadmap/issues/28
