I'm in favour of any, probably preferring mikerophonics since selecting a note in the ME should change track selection too. But they are so close it seems a shame not to merge them instead of having competing FRs. The key is that changes to active track in the ME should be reflected in the TCP.
This should optionally be with the Track List, Media Item Lane and changes in track/item caused by note selection.
The ME should also update itself when a focused track/item changes when using one per project. At the moment the header doesn't update with the current item and the named notes do not change to reflect the change in track.
What is really cool is that it's small stuff like this that is left to enhance the ME piano roll. Let's all go with this one since Breeder is an SWS knight who should be rewarded by the Kings once per season with an FR of his choosing.
