Facebook announces new changes today during their event. Now, you can download your stuff in one zip file. You have a dashboard for applications that makes arrangement of applications easier. You will create Facebook Groups where you can group your friends or perform group chat.
It is still very new. So, I guess the videos would be better to explain. BTW, as of this writing, the Application Dashboard and Download is still not yet activated on my account.
