This gives an outline of the location of the current view on an image. Eg if your image window is only showing part of an image then the Window Navigation window will outline the area viewed. You can "drag" the outlined square around the viewport and the main image will scroll. Additional a single click outside the square will center the image at that location. Also started to add additional information to a new page inside the Window information dialog (currently only pixel value is shown). Both these features are currently work in progress and unfinished. In particular the Navigator does not keep in step with changes to the basic image (however it does keep in step with image size changes and if you modify the size of the image viewing window). It also does not display the transparent areas of images very nicely.
