Thank you for making such a nice tool for the congregations. This app has become even better with the ability to grant different access levels so that more in the congregation can benefit from it.
With that said, would it be possible to introduce a feature that would allow COBE and LMMO to work on the schedules while not making it prematurely availalbe to other users? When the schedule for the week/month is finalized, it could then be "published" or "visible" to other users.
Another option would be to indicate that the current schedule is being edited or that it's a "draft" version that is not yet finalized.
Forgive my ignorance if I'm duplicating an existing request or I'm not aware of a certain feature that allows for similar concept.
