V6 Any way to hide the Contents pane?
 

V6 seems to have pinned the contents panel into the sidebar permanently - previously something that was toggled via a separate icon. I almost never use the contents panel, and find it tiresome to keep having to drag it to the bottom of the sidebar every time I open a doc so it doesn't get in the way of my canvas views. Is there any way I can turn it off until needed?

I think it would be reasonable for the sidebar to remember where the split is between the panes, so you could just drag the contents pane to the bottom and it would stay collapsed and out of the way there. But obviously it doesn't do that yet.
