As radioproducer using Audition (gosh, 20years+) you always have the problem that there is only one tempo per session. When you are working with music - as i do most the times - there is a constant need to adjust effects to the tempo of the song, musicbed or especially jingle (for a transition it almost impossible to get a clear and correctly timed solution).

Mainly this is the reason why we are about to switch to PT or S1. We are all set up to the creative cloud so AU would still be of some benefit but if its about the quality of the output - there will be no excuse for that.

And one maybe "pretty simple addition" would be a second timescale (USECASE Spots - working with bars n beats, and having a look at the seconds and minutes at the same time)
