We need to think through how the navigator scale thing should work, I  
think:

* it should be possible to set a min/max scale in the widget's  
<Extension>
* it could possibly do a better job of picking up default min/max  
scale from the map
* it should use a logarithmic scale for zooming, right now it is  
linear and is really quite useless

I just took a look at the navigator code, it doesn't change the  
position of the <div> that you put the navigator into.  If you are  
using templates/mapserver/standard to start from, you should be able  
to add:

<style>
  #Navigator {
     right: 10px;
     top: 10px;
  }
</style>

in the <head> of that page to set the position of the navigator (by  
default it should be at left:0, top:0 inside the <div> with id 'Map')

Regarding units, it is possible that the ViewOptions widget is  
overriding your individual widget settings, try removing it from your  
ApplicationDefinition.  Note that right now we are using quite  
inaccurate calculations for determining the decimal degrees of maps  
not in a lonlat projection and also for calculating linear distances  
from maps that are in decimal degrees.  We plan to incorporate proj4js  
especially for displaying the cursor position in lonlat when the map  
is not in lonlat, and it should help in measuring distances too  
because we can convert into projections defined in meters.

Cheers
