per-track markers

[Mark Edgington]

It would be nice to have markers which could be set which apply only to a given track. Then, various operations can be performed using these markers. For example: when a track is dragged, its markers could snap to the markers of another track (useful for synchronization of tracks), or one could select a pair of markers in one track, and another pair in another track, and have an operation which stretches or compresses one of the tracks to make the time between both marker-pairs the same.
