Logic for hiding activities from My Moodle is not intuitive

Currently different modules use different logic to determine whether they should appear on the My Moodle page. For example the assignment requires a due date and must be accepting submissions. I think it should be an explicit setting for the activity module to allow hiding it from My Moodle as it is currently unclear.

Hide from My Moodle [x]

This would require changes to all modules as it would also be confusing to only support this for some modules and not others.
