CS6 Multitrack improvements

There are a few nifty things in this version that you haven't seen before - read about them here.

One of the things that prompted me to jump ship to Reaper way back (chiefly for editing live multitrack recordings) was its ripple editing features.   A partly working ripple editing feature was subsequently added to Audition, but it didn't seem to me to be nearly up to the competition.  Has that been properly implemented yet (I wonder out of academic interest, being kind of out of the DAW loop these days)?  I don't see it mentioned in your linked article.
