The WordPress admin doesn’t have a favicon. That means that when you’re working with a bunch of tabs open, it’s hard to identify which one is for your WordPress admin. Well, Simply Basic has the solution – simply add one line to wp-admin/admin-header.php that calls the favicon of your choice:
<link rel="shortcut icon" href="<?php bloginfo('url'); ?>/favicon.ico" >
The only drawback is that you have to remember to redo this change every time you upgrade. It might be helpful if there was a plugin that did this for you (hint, hint).
