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.

Obvious Post States does what its name implies: makes the post states of your Posts and Pages stand out.
Post states like Draft, Pending, Sticky, Password Protected, etc. will be more prominent and obvious.
Takes into account the built-in WordPress Admin Color Schemes so everything matches.
Check out the screenshot to see an example.
