I just released a new plugin for Wordpress called Admin Favicon. It does just what it says: allows you to give your Wordpress administrative backend a custom favicon.
It's a simple plugin. It creates a new options page that allows you to enter your favicon's URL. It then sets that as the favicon for your WP-Admin!
Why would you need this? It's just a nice tool that lets you find your admin control panel much easier among all your open tabs. It's a simple plugin that I've had a few requests for. Hopefully you find it helpful!
