It would be really neat to be able to create customized notifications for the My Notifications page with a wizard, much like the way workflows are created. Workflows have their advantages and their disadvantages, just like the My Notifications messages. Sometimes, it's best to have a message come up before closing a document. Consider the case of a soft-enforcement of recommended fields. If a recommended field is not filled in, creating a custom message upon closure of the document might be a good way to warn the user of this.

I recognize that the development of this is possible in AL, but we're not all developers :).
