So I downloaded the new Facebook Desktop Notifications applet and it's great! It's just a Facebook icon in the menu bar that turns blue when I have any notifications. A little pop-up also comes up in the corner with the text of any comments. It's great and there isn't any actual "application" that needs to be running... it's just a menu icon and runs in the background. Is there anything like this for Twitter? I know there's things like Twitterific and TweetDeck, but I don't want an actual desktop application. Thanks!
