Something I'd really like is a way to expose CSS styles to the editor easily. One of the major problems I always run into is that my customers try to make things look like the rest of the website by hacking the text a bit.

They'll see a highlighted word or sentence with a bold font, wider spacing and a blue background. So they set the background blue, the font bold and the spacing wider. But really, the editor should provide an intuitive way to apply the <span class="highlight"> element.

Some editors out there do this, but they generally suck in other areas. Wysihtml seems to apply inline CSS. Can it easily apply a class too?
