New FaceBook layout

The FB admin has never announced of the changes of new layout. Actually I hate a new outlook, but quite same as the old ones. But I don't know how to revert back the old style on the left hand side. I can't bookmark my favourite news feed like Mafia Wars, Castle Age, Mousehunt, etc... I hate FaceBook administrator for not giving permission of changes to those FB users might be affected.
