I suspect compared to rendering maps this takes 0 time even just linear. I would code linear and leave it until proven slow (had I spare time :-)). >>> Possible improvements can be: >>> >>> .

ATM there's no choice in the matter (although > if in realtime tracking mode - it doesn't auto view the downloaded gps > layer data - since it just jump to the GPS current position anyway) I guess I meant that "acquire and show gps real-time track" and "follow it" are logically separate things to want to do. >> What about changing the default to zoom from pan?

Putting tracks/waypoints specific stuff in the global layer menu feels too crowded, but whatever is ok really.
