This plugin allows you to include a list of revisions when viewing a list of posts, pages, or custom post types in the admin dashboard. It can be configured 
to limit the number of revisions shown, the post types it is enabled for, and a prefix & suffix to wrap around the revision title to offset it from the rest of the list.
