This is an easy to configure addon the get rid of that mess of buffs, that covers half of our precious screen space since the last patch 3.0.2.
To hide a buff, just SHIFT-Rightclick it. SAF will remember which buffs you hid between sessions.
There is a profile management integrated into Blizzard's interface options panel.
