Online social network Facebook is now offering its users the opportunity to preview and test new features and functionality before they are made available to all of Facebook’s 80 million members over the coming days. In development over the past six months, the redesign includes an integration of all of a user’s various feeds in a single stream of updates.

The user is free to make any layout according to his convenience. PageRage currently works with Internet Explorer 7 and Firefox 2.x & 3 on Windows XP and Vista, as well as Firefox 2.x & 3 on Mac OS X. The work is going on to make it compatible with Internet Explorer 8 as well as Safari for Mac. Other users who are using PageRage will be able to see the changes one makes to his Facebook page, but in the near future there will be options for users to change things that only will see such as changing the look of all Facebook pages and so that his changes are apply will appear on all the pages a user views.

We can also expect a release of a new version that will enable users to change their view of other pages to enable the ability to add a layout that shows up on all of the pages that a user views, although these layouts will not be visible to anyone else.
