Fixed Width Admin

This plug-in makes your WordPress admin area fixed width instead of the default, elastic. This is perhaps of the most utility to users with larger monitors who enjoy rocking large browser windows, but do not enjoy trying to compose a post in an editor that has line-lengths of more than 200 characters. Why is this not an option in the default WordPress install? We have no fricking idea. But now, at least, there is an easy solution. http://ogilvi.es/fixed-width-admin/

Customization

You can easily adjust the width of your admin area, its alignment, and the page background color that appears to the left and right of it. Inside the plug-in folder is a file named wp-admin.css, simply open this file in a text editor, and make your changes. All the code has comments that explain the specific functions—don’t be intimidated, just experiment, and if you go too far you can always re-upload the original file.
