A very simple plugin. Probably took not even 10min to make it but is a life saver for everyone who plays games on Facebook.
This removed the HORRIBLE LEFT BAR!
I was using this for long time but realized that might be everyone who plays FB games might need it and so released it on the Chrome Store.
So right now this works only for facebook games. If you want to declutter any other website then drop a note in comment. I might be able to add the feature in next version.
