Currently the Send message for the creator and the Mark as reviewed processes are intertwined. A reviewer can only send a message to the creator if the page is not already reviewed. And the button to send message to creator also acts as a mark as reviewed button. These two workflows should be separated because often reviewers need to send a message to the creator without marking the page as reviewed (such as when it's still under review).
- When user hits Mark as reviewed, that only marks the page as reviewed and does not send message to creator.
- Add a new button Send message to creator which sends a message to the page creator if there is text present in the textarea. The button is disabled if there is no text.
- Position the elements according the mockup above (with a horizontal separator between the two different steps.
- The checkmark on the tab turns green only if the page has been marked as reviewed (no relation to whether a message was sent to creator).
