Change your Edit Comment page

Go to the "wp-admin\edit-form-comment.php" you can find all the div related to the design.
and the css are using "wp-admin\css\wp-admin.css", "wp-admin\css\global.css", "wp-admin\css\colors-fresh.css"

in the above picture you can see both are same but in the Approved there have a number in the second picture. It is a very small trick. if you want to do it go to the "wp-admin\edit-comments.php" line number 240. You can see this code
"'approved' => _n_noop('Approved', 'Approved')," now you replace this code with this
"'approved' => _n_noop('Approved (%s)', 'Approved (%s)'),"
you can see the change
