MartinK, this is a feature request:
Can u please add a location based alarm? ie, if we mark a point, when our position comes within, say 100m of that point, the alarm goes off.
This will be useful for people in trains or other public transport, where one may doze off and miss their destination. In this mode, the gps need to be polled only every minute or so.

What do you think? Is it possible?
