UI Fail!

I understand tweeking and developing new ideas for a product, but this latest update to Camera Raw is horrendous. I can't even begin to find the functions I use most frequently. What's worse, the older versions don't even appear to be available. You have made what would have been a 20-minute project undoable! I need to be able to directly control how much of the image will be affected by a change in noise reduction. I also want the old cuve function back.
