You can also get native Ubuntu notification bubble for news alerts from your favourite news site or access Google Docs from dash itself. While using the Web App feature, you can use “Alt + Tab” to switch between these webapps/sites similar to what you use for regular Ubuntu apps. Initially, this feature will support only Firefox and Chromium but we can definitely expect it for other popular web browser soon. The official video from Ubuntu explains it better: http://www.youtube.com/watch?v=x7vF-AB7SF4

How to install the Web App feature in Ubuntu 12.04:

If you are eager to get your hands on this exciting new feature, you can install it using a PPA as it is not yet available in Ubuntu Software Center (not even in Ubuntu 12.10 development build). Use the following commands to install it: It is approximately of 105 MB in size. If you want to speed up the installation process, use apt-fast instead of apt-get.

How to use Ubuntu Web Apps:

Now when you open Firefox or Chromium and open a website that is supported by Ubuntu Web App feature, it will ask for your permission to integrate it in Ubuntu. For example, when you open Gmail, it will ask for whether you want Gmail to be integrated:

Once you integrate it, you can see all your Gmail activities in the messaging menu like this:

As you can see, you can change the Gmail chat status, see the number of unread mails in different folders. You can also compose new mails. Similarly, you can integrate music streaming services in to Ubuntu and control them directly in to the Ubuntu sound menu. Take a look at Grooveshark inegration:

Note: You need to be logged in the respective website otherwise you will not be asked for the integration. Also note that not all the websites are supported (as of yet). Though list of websites currently supported by Ubuntu Web App are available on the web. The Web App option will NOT be coming to Ubuntu 12.04 LTS any time. It will be released with Ubuntu 12.10, thought it will be optional and will be available for download in the software centre. What do you think of Ubuntu Web Apps? Is it something which you were missing in Ubuntu and will be happy to have it or you will avoid it and prefer to have a clean desktop rather than one cluttered with so many webapps?
