There may be some parallel with the discussion earlier in the year about graticules as map/composer decorations versus layers: http://lists.osgeo.org/pipermail/qgis-developer/2012-May/020040.html http://lists.osgeo.org/pipermail/qgis-developer/2012-May/020047.html http://lists.osgeo.org/pipermail/qgis-developer/2012-July/020854.html For ease of use on a basic level it seems to me that instead of being a separate layer it should be some sort of symbology option tied to the original map layer, similar to how it works in Mapinfo. If you need a different feature in the layer to act as the mask for each page in an Atlas, I don't know the best way of controlling that, but I think the same problem would need to be solved for other things like map titles.
