Gmail’s latest feature, the Preview Pane, allows you to simultaneously preview emails while reading or replying to others. After several hours of use I’ve found this to be one of the best improvements to Gmail in years.
The only issue I found with Preview Pane was how the “People” widget and advertisements on the right of the page now waste a lot of valuable space (202 pixels on the vertical split, and 225 pixels on horizontal split).
This user script (for Chrome, or Greasemonkey for Firefox) removes that sidebar, allowing the preview pane to extend to the full width of the screen. Enjoy the extra space!

-Fixed: Now works for Chrome 27
-Fixed: Images automatically resize to fit preview pane on Chrome
Gmail appears to have a bug with the Preview Pane lab, unrelated to this plugin. If you have Preview Pane turned on and Snippets turned off, the message list will appear distorted. I have submitted a bug report to Gmail about this. A temporary workaround is to enable Snippets (under the General tab of Gmail settings)
