The other day the folks at Google launched a new Gmail Labs feature called Title Tweaks that lets you decide whether your browser title bar should read "Gmail - Inbox (20)" or "Inbox (20) - Gmail." This is a feature that's been a part of Gina Trapini's Better Gmail 2 add-on for Firefox for a while, but now that it's officially part of Google Labs, you can set your preferences once and they'll apply no matter what web browser or computer you use to check your email.

But there's one thing that the latest version of Better Gmail can do that Google can't... yet. Better Gmail 2 now lets you see how many unread messages you have right on the favicon. This takes up a lot less space than the typical Inbox notifications in the title bar. And that means you should be able to see how many unread messages you have even if you have dozens of tabs open, or if you're using an add-on like Faviconize.

If you don't want to install Better Gmail 2 for one reason or another, you can get the same effect by using the Unread Messages Count in Favicon userscript with Greasemonkey.
