Thanks Bob,
Yes I am aware of this workflow.
What I'm looking for is an elegant/simple way to quickly cycle through lots of regions and seeing their waveforms without needing to click the mouse, which will break the speed of this.
It's a little funky request, but it's sometimes very useful to be able to hold the up or down arrows and let the waveform cycle through a whole bunch of regions. It almost becomes "stop motion" of waveform redraws that can really help with determining quality of edits and overall volume.
Another thing that must be in place to make this work is for the Sfile view to allow a global horizontal zoom levels to all regions.
Not sure if it's worth it for you to add this functionality but I use this type of feature often but I would need to use a different audio file browser tool just for that.
