Could you make the app version history visible to admins? To use these apps in an ISO 9001 environment it is required to have documented changes that include, version, date changed, who changed it, and if possible what changed. I am pretty sure you know the version, date modified, and who saved it it is just not visible currently. The "what changed" could be a simple user input to a note box. This also allows developers a way to track changes as well.
