Can be used for more than just controlling width

As anyone whose worked with the visual editor knows, the way content appears within it often bears little resemblance to how it will actually look on the page/post. The appearance of fonts and other things may not be the same, In other words, what you see isn’t really what you get. This can sometimes be a big hassle, requiring you to do multiple previews to get the content to look right.

I wanted a way to fix this, to make content in the visual editor duplicate the way it looks on the actual pages/posts. I was doing so by editing the styles in wp-includes/js/tinymce/themes/advanced/skins/wp_theme/content.css, but, of course, that meant that I would have to redo the edits every time I upgraded WordPress.

Happily, this plugin gives me another option. With it, I was able to change the font face, size, color, and line height, as well as image padding and some other things to match what shows on the page/post.

I think it would be great if the author of this plugin expanded its functionality and turned it into a way for people to fully control how the visual editor displays content so that they can do what I did.
