Comment 7 for bug 851313

I'd argue for removing of these buttons, because Dash in technically not a window, but a dock or toolbar or something in this vein. It's also problematic, because when user opens Dash, the buttons to close/maximize Dash appear exactly at the same place where were the window buttons (if a window was open). It gives us two levels of window buttons (and Dash is partly transparent, if you remember) and is confusing. For consistency reasons, there shouldn't be window buttons on Dash.
