One thing I often hear GNOME critics complaining about, usually with Nautilus' busy headerbar area as the primary example, is that its client-side window decorations don't leave many empty spaces for dragging the window around.

What most critics don't realize is that the entire window headerbar area remains draggable. You can drag any of those toolbar widgets to move the whole window around with it, as if those widgets weren't even there. The right-click menu works, too.
