I never implemented generators as anything but effect layers. I also wanted to 
have them as input for drawing tools and as a fill option in the fill tool, 
but I'm not sure I ever implemented that. I don't think we need them in a menu 
like the filters, though.

perlin used to be in Cyrille's krita/plugins project -- www.krita-plugins.org.

It's possible to switch individual channels of layers on and off, but right 
now that's limited to channels that are in the colorspace of that layer. And 
it doesn't seem to work, though as of today, it's saved and loaded :-)
