Since this site is dedicated to providing wiki compare, I provide another tool similar to this. It is called SharePoint WikiSharePoint Wiki Redirect.
Below are its features：
* Control which version of a wiki page is displayed by default;
* Quickly toggle between the most recently edited version and the latest approved/published version of a wiki page;
* Set the version history page as the default view, displaying all other versions in a clickable list on the left;
* Can select views from which to redirect.
Again, If you need more information please visit http://www.sharepointboost.com/wiki-redirect.html
So this works more or less like Flagged Revisions for MediaWiki then?
