UX suggestion. You don't need the "as read only" save options if when you do a normal save the page tells you if it has been changed. That'll get you down to 2 menu options and make me think less.
The "as read only" options produce an HTML document that lacks the editor features - when you open that file from your computer, you'll see static content (although it just changes a couple of HTML attributes and leaves all the JavaScript in, inactive). The normal options re-create the entire page - editor, content and all.
