You must've read my mind.. or I read yours. I was thinking about the possibility of creating a specialized browser, like Flock is for social, or Songbird for music. But I was thinking a specialized web browser for Google Maps navigation,

I was also thinking that it could use the location of your GPS if you wanted to use it for navigation. E.g. you can use the browser to set the route and then a gmap to gpx bookmarklet kicks in to convert the instructions into code which would run in the background. Then as you drove along the route, as you hit the appropriate GPS latitude,longitude coordinates flite would tell you where to turn.

Edit: I was also thinking about ways you could refresh the view, but it doesn't seem likely since Google could change your directions even if you could automate the entering of your current GPS location into the A box.
