Great Piece. I've done something like that with textfields and FieldsetTab. But a Out of the Box Solution is quite nice. A client had requested once, a SEO traffic light, which checks different basic things like the Title, Image Description, Keyword Density, List of the actual keywords in the existing text etc. In my opinion you can achieve this as well with a small SEO cheatsheet and a bit brainpower. But on the other hand, it might be helpful for user, with less Web/Seo Knowledge. Would something like that be possible? Or is something like that already in your mind?
