Surely, if a group of tracks is time synchronised, then any action
which changes the timing of the audio has to be applied so that all
existing synchronisation is unaffected. I think this simplifies
things, and makes it easier for the user to get a hold of whats meant
to happen. It also ensures that all labels remain is sync, which is
impossible otherwise.

So for example:
1. If an effect which affects timing is applied, such as changing
speed,  then it has to be applied to all tracks (including labels).
But, if desired, effects which don't affect timing could be applied to
only the selected tracks.
2. If you want to time shift audio, then all the audio and all the
labels have to move. So if you try to time shift a single clip, then
in fact everything moves. (Though you can of course move labels around
without affecting the audio).
