We'll create fresh WordPress site with Pending Comments Highlighter installed. You have 20 minutes to test the plugin after that site we'll be deleted.
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.
