If you’re a Mailplane Clean CSS user, I’ve updated the stylesheet for those of you who’ve enabled the preview pane lab feature. This will make the message body fill the entire space where the people widget was. I’ve also cleaned up some of the code in the file to make it more user friendly.

I’ve started hosting the project on Github, so you can download it directly from there now: https://github.com/jimmitchell/mailplane_css/. Just click on the “Download” button/link on that page.

Questions or bugs, note them in the comments.
