I LOVED the new version because it made navigating and sorting through my huge task lists so much easier. I was carefully avoiding upgrading until today when I accidentally hit the upgrade button while selecting other apps to upgrade. NOOOOOOO! I wish there was a way to get the "new" version back. I hope you can work out the kinks soon.
I think when you switch UIs you hear more from the people who don't like change than you do from people who do like it, and that may skew your perception of the overall. I for one am dearly hoping the layout features of the new version return soon.
