I say keep it. I’ve just been doing a load of editting, and used it a fair bit.
It’s useful in looking at wave forms, selecting a portion and zooming in, etc, and knowing that it’s non-destructive.
It could be kept, but not a default on the menu bar – but outline it’s function in all the help files, and how to add it to the menus.
I understand it, appreciate it, and use it. Most sequencers I have used have this facility, going right back to Atari days, and it is a logical part of knowing your track – and essential when exploring someone elses!
I voted KEEP IT!!!
