Absolutely. I believe track view was released a bit early, but no regrets as it is still very useful. Definitely needs to be completed.

I speculate, a part of the challenge is that position of tracks are tied into position of the tracks in the mixer (and I am sure some internal stuff too)... I will just add a small item to your request. If tracks will be "movable" consider mixer track position synchronization too. So mixer reflects the order of Track View.
