The GPS marker displayed on the map will have a velocity vector drawn on it; this is at least a graphical representation of what you're asking for. I'll consider adding a text-based representation, but I'd really like to keep the map display purely graphical (no text).

There will be a menu action called "Download maps along route" that will download all of the maps (at the current zoom level) that would be required for the currently loaded route. You would have to run the command multiple times to get the map data for multiple zoom levels.

There will also be an action to download all maps within a certain rectangle of space (defined by lat/lon). This can be used, for example, to download all of the maps in and around Portland, Oregon.

These operations may take some time on the Nokia 770, but they'll be threaded off, and there will be a progress bar, so you will still be able to work with the program while it downloads the maps.

Hopefully by Monday, but I do have a full-time job (and a full-time girlfriend), so my availability sometimes wanes.
