Thanks, Midnight Blues, unfortunately now the "per app settings" is only good for Pro version. GMD hide soft keys was also recommended for hiding the nav bar in igo. If I were to buy the Pro key, which app fits my purposes better? I did not find the per app setting in the GMD hide soft key, and they cost about the same. I can only envision this being useful in iGo and Waze.

As for the Zip edit, I was opening it up with winzip in windows 7, edit the ini directly and save it directly to zip, so no upzip/zip process involved. But it sounds like this is a scaling issue that can't be fixed by simply adding the unusual resolution in to ini, and furthermore, I actually prefer the full screen while navigation. I guess I will try to get the nav bar hide done, and enjoy the full hd screen in igo. Thanks a lot.
