Might be nice to do some more input validation, particularly for links - the editor is happy to insert a javascript: link. I don't think this poses a security issue (at most, you'll get what - a self XSS?) because you'd obviously do server-side sanitisation in a real application, but it might be nice to check for non-https protocols and warn the user when they insert them?
