Moving the sidebar collapse/expand button?

[LostForWords]

Is there a way I can move the sidebar collapse/expand button away from the sides of the forum and perhaps above the sidebar (like how IPB has it?).

I'm trying to make a 100% width layout and the positioning of the button means a horizontal scrollbar is always added because the button bushes the layout out.

I'm not sure if the coding for the button is in a template or a file.

I worked this out myself, you want to edit the 'sidebar_button' in the homepage.css for future reference.
