When following a route (or track) it would be really fancy to automatically zoom in on a waypoint when getting closer to it. And when your past a waypoint to zoom out to make the next waypoint visible on the screen. When cycling a calculated route I find myself doing this all the time. It will also help to notify that you are nearing a waypoint.
This should be optional off course and easy to switch on/off. Maybe the centre button can be used for this, so this becomes a three state button (off / centre / auto zoom).
