Sorry, no options for downloading routes for either garmin or magellan. I've never found a use for it personally, but we can consider adding the functionality. I make my routes on the computer and then upload. I find linking waypoints on units themselves too cumbersome.
As for line width -- I agree completely. It needs to be in there, as selectable for each track, or each file as a whole. I often hack the source code to do line width for various mapping projects, figures, etc. An option would be nice.
