[feature request] A merge layer function in BackBone

hi ppl! :smiley:

First … GREAT Tool!
But I was poking around with a sound and had it separated into tonal and noise when I noticed I hadn’t done a particular good job of getting them separated so there was still tonal residues in the noise. I tried again and got it separated like I should have done in the first place. But … now I have THREE layers, one with clean noise and two with different tonal artifacts. It would be great if we could have check boxes to the left of the layers in the layers pane and a [ merge layers ] button. Then I would be able to unite the tonal stuff and edit onward with just one simple single tonal layer and one noise layer.
