Well that's how quick mask works in the gimp and photoshop as well. Unless I 
have missed something. In fact the biggest problem about intuitivity with 
masks in krita is that don't really appear in the UI. That's what we are 
working on for the next version, having mask visible in the layerbox, that 
way it will be very clear wether the mask is a children of a layer or is in 
the layer stack.

You can't yet. It's one of the biggest problem currently. The goal is to make 
it possible to easily drag and drop mask and selection in the layerbox. But 
your comments seems to indicate we are on the right track for next version ;) 
Even if that mean that currently you can't make your work correctly :(
