Expand the draggable area for the window on Mac

With Dragonfly putting the timeline titles so close to the very top of the application window, clicking and dragging to reposition the window very awkward. It's not difficult to accidentally switch timelines when trying to move the window to a new location on the screen.

Instead of clicking and dragging on the very top of the Dragonfly window, I am frequently clicking and dragging on the left-hand sidebar to try to reposition the window. Unfortunately, that does not work, and it sure feels like it should.
