Then I installed the (faster version of) the plugin , launched it a few times, but no layers appeared . Finally RTFM the short description ... channels . It seems it makes channels not layers/layer masks!
I''ve not really used channels . My guess is I do channel to selection , then make a mask for a given layer from the selection?
When you add a mask to a layer, you can initialize it from a channel: see the "Channel" button at bottom of the list, and the selector below, that contains the current channels, except the 5 implicit ones: R,G,B,A and selection.
The difference between channels and layers, beyond channels being just grayscale, is that channels always encompass the whole canvas.
