I'm sorry; I don't remember the specifics of the Scribble page now. I remember it was something to let you take graphical notes on GPS, but I can't find the page you were referring to.
I haven't done much more with GPS. All I've done so far are some simple scripts to translate a route into normalized coordinates to display on a map, one that monitors your distance from a starting point, that sort of thing. I have been using Navit.
I think my next step with the GPS is to profile Pyroute some and see if I can get it working at a usable speed. I planned to put any improvements within Pyroute, assuming I can get it working reasonably on the neo. -- User:Wurp
