Third option candidate: Make track layers read-only by default?

What is that rate, how many seconds does it wait for a new track point?
Sounds like 5 seconds or more. Maybe the track splitting could be done
by time, not by distance? Or by both. If delta_time > 1 minute and
delta_position > 100 metres, then split the track. That should do well
enough for both time-based and distance-based track recording. (I always
record at 1 point per second and that gives me a huge number of points
that tend to overlap in the display at walking speed... Hence that "GPX
node zoom" patch...)
