Comment 10 for bug 762277

As discussed on AskUbuntu: http://askubuntu.com/questions/81175/how-can-i-always-show-the-close-minimise-and-maximise-buttons-on-their-windows I proposed kind of idea which I link also here.

Design is only informative so it does not look good, but here is how it's supposed to virtually work: If user hovers near top left region (not including global menu or launcher panel) then this floating control to pop-up allowing user action on background maximised window. Similarly how overlay scrollbar work.

I guess it's far from perfect but anyway...
I also like proposed idea from bug report, of embedding window controls in Unity launcher quicklist (for running applications) which will also allow controlling windows that aren't even visible
