Google Chrome extensions have brought features to the browser and coupled with the awesome speed Chrome has, this gives us an amazing overall browsing experience. I have personally switched over to Google Chrome as my default browser and am satisfied with it.
Google Chrome extensions now have an added advantage. Chrome got a nifty feature of extension notifications whereby any installed extension can send out windows style notifications. This feature was already available to websites from Chrome 4. In the latest build, this feature will be made available to extension developers by a notification API.
One of the first to use this notification is the Gmail notifier add-on for Google Chrome. This added feature into the notification API can mean two things.
The advantage of this is that extension developers are no more limited to OS capabilities to display notifications and can easily do so using the browser. This will get clearer when more extensions use this feature to create a better user experience. Facebook and Twitter apps will be the first to follow.
Though, a downside of this is how extension developers will use this to provide some real functionality or simply for creating annoying notifications.
