We do plan on adding the auto-advance feature (as well as other features from our new music page improvements from the website) to the iOS app.
With regards to the disappearing measures before feature, we were recently informed that we unknowingly violated a patent so we had to remove the 'before' feature. You can still do the disappearing measures 'after' feature.
I agree with Kirk. Don, I hope the developers are working on a solution to re-implement this feature, rather than just sitting back and saying, "oh well."
