User Interface: Remove Whitespace

[abhinav-goyall]

It is more of a UI best practice thing. Lots of whitespaces on both sides of the screen. Can have a side bar containing list of all useful links or you can say as quick links. Also Can a have a menu like thing which will show a list of items like The Champion ,Implementation Strategy etc.rather than listing out separately below under topics tab.
