It would be nice to be able to see the zoom level at which one is viewing. Such as 25,000:1, 15,000:1 etc. Furthermore, it would be nice to select a zoom level, perhaps from a drop-down menu, rather than iteratively clicking zoom in or zoom out. Also, it would be nice to have user-defined zoom levels possible, such as inconjunction with route planning or just plain having a 'home' zoom level.
