The Google Chrome team is launching beta support for extensions today, and we thought we'd take a shot at writing a Reader extension. The Google Reader Notifier displays the number of unread items in your Reader account in Google Chrome's toolbar. When clicked, the toolbar icon displays a popup preview of the latest items in your account. This way, you can keep an eye on your Reader account wherever on the web you are.
Note that extensions are currently available only for the beta channel of Google Chrome for Windows and Linux, so you'll want to make sure you're running one of those browsers before you install the extension.
Reader users may want to try the RSS subscription extension too. It adds previewing and one-click subscribe support for any RSS or Atom feed that you happen to come across. And feel free to browse or search for other handy extensions.
