If my memory is right, there used to be one, but I have removed it some time ago. The decided so, because there does not seem to be a right place for it in the window. And because navigating in the main editor is so fast (zoom in and out by rotating mouse wheel, when zooming in the point under the mouse tries to stay there; move the image by pressing and holding the mouse wheel and moving the mouse).
There is a way to get the navigator window back, but it involves reconfiguring the layout. I can do it for you, but I still do not know, where to place the navigator panel in the main window.
