Gmail, Google Reader, Wave And Voice Notifier For Google Chrome

The extension development for Google’s web browser Google Chrome seems to be in full swing with new extension being uploaded daily to the official extension repository. Extension support is still limited to Google Chrome 4 which is currently only available as developer releases. Many experts assume that the development of extensions will get another boost once version 4 of the web browser is released officially by Google so that the general public can download and install the browser.

One Number is an interesting extension for the Google Chrome browser that acts as a notifier for the four Google services Gmail, Google Reader, Google Wave and Google Voice. It places a single icon in the web browser’s toolbar that displays the number of unread messages as one number.

The main benefit of this approach is that it saves up space in the Chrome toolbar if several Google services are used regularly (the extreme would be a reduction to one icon from four).

All four Google services are monitored by default. The options can be used to disable checks for specific services.

The first step after installation is to log into a Google account by left-clicking the icon in the toolbar and selecting the Log In link there.

The login redirects to the Google account login on the Google website.


The same menu contains a link to the options which can be used to disable and customize specific services (changing the color code or excluding their unread count from appearing in the number that is displayed in the toolbar) as well as server query intervals, timeouts and misc toolbar colors to indicate if multiple services have unread messages.

One Number is a Google service monitor that can be helpful for Googleholics who use at least two of the services that are currently supported by the Chrome extension (it’s also good for monitoring only one service but that would defeat much of its purpose).

The extension is compatible with Google Chrome 4 and can be downloaded from the official Google Chrome extensions website.
