Hi, thanks for this plugin it is very useful and exactly what we were looking for.  I would like to add a functionality where users can add a note or title with their revision that I could then list in the Post Revisions table.  Right now revisions are identified by date and that is not very useful.  I am comfortable w/ PHP so if anyone can point me in the right direction that would be great. Thanks

If you want to take a stab at it, I suggest storing a postmeta record via metabox input. On the Revisions list side, take a look at revision-ui_rvy.php, function rvy_list_post_revisions
