Mal,

I am sorry you feel that way, I have a completely opposite view.

1) Regeneration times are now almost instant.
2)Non-Modal MTP (Multipicker) Library lets you browse RT's with near instant placement right in your tune, so you can audition actual rendition of it on the fly. Not only that, you can switch whole styles on the fly.
3)MTP Library opened up a lot of MIDI and other content that was hard to get to and just made whole process of searching and browsing 10 times better.
4)Several other tools became non modal, so workflow became much easier and less restricted.
5)With track view and CTRL+F8 you can regenerate any part of any track on single screen super easy and fast.
6) A great selection of new content. I do understand that it is a thing of taste.

But as far as program goes:
With a few shortcomings and about two dozen of known issues, that I sincerely hope will be ironed out in the next month, in my view this is one of the best updates ever.

If anything, workflow improved significantly.
