To try to bring this back to the UI/UX topic, as usual Charlie and Dan are technically correct.
I thought MarioD request:
"Wouldn't it be nice if we could drag and drop an audio track or tracks into the track view? This could take the place of the ACW and all of its problems." was really a plea for improved UX.
It has at its core what I have been requesting nonstop for three years. UX user experience and workflow are really the same thing.
Hidden in the request from my perspective was the idea of making the tempo track a global thing that worked equally well in all views.
It was not a matter of can it do it?
It was a matter of improving the user experience to make the main views more of an integrated workflow process rather than a bolt on.
Make the Tempo track global along with ability to do tempo mapping. A global track on top of any view would correspond with that view whether it be audio, MIDI, or Generated players.
Another global request to Make the Arrangement a global track to better keep track of the arrangement globally in all views.

Let's not lose track of the PGM UX request for input.
