use layer as if mask was applied

Description
When a layer has a mask, there should be a mask-lock flag that, when enabled, causes all actions that would normally take place on the layer or its mask to take place on the image that would result if the mask was applied. This would be extremely useful, if, for example, I use a mask for the translucency of a bubble rendered, and want to copy the translucent bubble. Currently, I would have to apply the mask first, which is aggravating. Drawing would go to the layer, not the mask (or it might be optional, maybe you could still click on each one as the focus, but anything reading the layer reads it as applied).
