Feature Request: reset flow on change

[JurgenG]

Imagine an article written by Author, it has to be reviewed by Legal and by Marketing.

In an ideal world, if Legal changes something, it should get reapproved by Author and the workflow should need to start over again. So if Marketing changes something, it goes back to Author, then to Legal...

In a more ideal world, it would even be possible to see the changes highlighted. But even the first step would be something that would make me really happy.
