The way I see it, I would select multiple with the select tool in the Playlist window and select "Normalize" from a "Multiple selected" window...
The same thing would be useful for functions like "Auto Name", for example.
Another one:
when you right click on a channel on the channel rack you can chose "assign to new instrument track" to create a new instrument group. is it possible to do this for multiple channels all at once, instead of having to right click every single channel?
