Hey, I have been looking now for a while but can someone give me some code example how to add some custom classes into the RCE menu.  I would like to extend the Rich Content Editor bar with some custom CSS classes which have been put into the theme editor. It would be nice to provide some easy dropydown button or expand the current Format selector.  rather dan telling a user how to edit the page in editor view. I found some great CSS stuff but providing this to the end-user would be nice.
