Looking at all of the different feature request posted for "Share for Review" I feel it would almost be better to just merge the "Share for Review" features into the "Publish Online" since it already has many of the requested features like setting PDF quality, being able to select the number of pages, print as spreads, ect... The only thing it is missing is the ability to make it invite only and the commenting features. That way instead of two tools there is one. Maybe it has an option that when selected it adds the "Review Features" and if not selected it stays as a Publish Online document.
