I'd upvote this request forever. Premiere doesn't update waveforms for any effect added and it is really weird.. What's weirder is that if you apply a preset in Essential Sound then it does! If you were to apply a dialogue setting and then one of the presets, it will change the waveform to see what you get out of that. Other than that, there is no way to affect the waveform visibly. Why would that be? Or am I missing something?
