Control volume of each layer separately
I think it would be nice if we could control the volume of each layer seperately. This way you can edit individual clips and bits of sound on a layer, but then decide to augment or reduce the whole layer while keeping each clips individual setting on that layer.
Example, I have a layer with many voice clips, one ohter with music. I might want to reduce all the music tracks at once to let the voice pop out better. At the moment i need to do each clip individually.
