I have found a very annoying problem on the admin panel.
Where the comments are listed, unapproved comments had lightyellow color (HEX:FFFFE0). 
It is hard to make difference between unapproved and approved comments with this color.
This plugin changes the background-color to orange [#DD823B] (from WordPress 3.8 Sunrise admin color-scheme), and the author’s name and his comment to white. This makes the comment approving system easier to see on all monitor types.

Pending Comments Highlighter

This plugin overrides the default pending comments background color in WordPress admin.
