As an editor (or super-editor, depending how your ahead permissions set-up looks like) you can mark content as must-read. That allows
- editors to track who has read certain content and who hasn't read it yet
- users to confirm that they've read a document already
- users to track which readings are mandatory ones
Ideal use cases are very important content, and content that requires complicance with regard to mandatory reading, e.g. safety measures or price lists.
