Hi, I thought you should know that when I'm in the page editor screen I get an alert pop-up that says "undefined". I also can't seem to get things to work, like "insert into editor", though "edit in library works". I only played around with it for a brief time, I've decided this plugin doesn't fit my needs as it is now. It's a great idea, though, I'd love to see this continue to be developed!
