I am 110% rooting for this feature to be available.
I am using Dataform as a Document Management System. Two of the fields are a File Upload (file field) and a Version Number (text field). Last week, a user asked me this question, "Does this mean that I have to login to Moodle every time to check for latest version?". My answer was "yes", because at present, a Dataform notification message does not include a field value. At present, the user can know that a row was added or modified, but not in detail.
So, I am trying to find a way to assist my users to know exactly what update was done on which file (i.e., which document in the Tabular View). The enhance notification rule will definitely be a good solution.
