Add a way to collapse or hide the main interface, while keeping all the individual panels open.

[allista]

Could we get a way to collapse or hide the main interface, while keeping all the individual panels open on their own? I'd like to use the heading control as my primary SAS, and the little detached window works great for that, but the main interface staying open covers a lot of screen real-estate. Maybe just have the secondary windows stay open if the main is toggled from the toolbar, and you can just close them with their own "x" if you want them gone too.
