It doesn't work for the case when you do have waypoint markers.

I also do need a marker to store the information, unless I completely 
re-engineer the way layers work - the audio information is stored in the 
markers, not the layer. Yes I could do that re-engineering, but it would 
be a much bigger job.

However, I thought about this yesterday, and what I can do fairly easily 
within the framework that exists (plus the ability to move drag play 
head) is to have shift-drag create a marker at the point you release and 
apply the synchronization to it. This pretty much does what you're 
suggesting.

So, with a suitable tweak to how markers are dealt with in the first 
place, you'd end up with two markers - one at the start of the track and 
one at the sync point (more if you have more than one sync point of 
course), and the sync the way round you want it. I think I'd also change 
the waypoint case so 'Apply Audio' works for both off the GPX layer.

I'll try doing that soon.
