Do you know that you can filter Live/News Feed from your friends according to specific applications? As example, you play Farmville daily and don’t want to miss any chance of getting Mystery Eggs or adopting strange animals from your friends. By filtering feeds, your wall will display everything updates/news they publish on Farmville.
My filters, as you can see in this picture, it has Cafe World and Farmville shortcut, so I'm 1 click away to everything related (cafe world - free food!), the problem is I forgotten how I did the shortcuts. What annoys me is that sometimes those shortcuts disappear, and then appear back. Crazy facebook!
So the manual way to make your own filters :1) Go to your favorite application. I'm using Restaurant City as example here.
2) Look for the application ID in the address bar. [See example in red circle]. Restaurant City's ID is 43016202276. Copy n paste it somewhere.

3) Use this link, copy n paste in the address bar :
http://www.facebook.com/home.php?filter=app_
4) Paste the ID at the end, so it will look like this :
http://www.facebook.com/home.php?filter=app_43016202276
(this is for Restaurant City)
You might want to save all your filter links in notepads/browser home page/bookmarks etc for easy access. Remember to stay logged in (facebook) for the filter to work. Please note, if you have blocked some application, the filter will not display live/news feed related.
