Like the title says, I'd like to be able to hide the sidebar in a sliding menu. Where a click would give permanence for those that want it by default, but another click would hide it to the side where it could be activated.

Some might like it, some might not.

I run my windows horizontally across the screen(tabs) with what I'm doing. Fic in one, chat in another, browsing in the last. When you do that on the forums, it squishes up the front page of the forms and it bothers me, so I'd like to still have the functionality of the sidebar, but choose when I want it to appear.
