[Qgis-user] Control Layers using Atlas

[Alexandre Neto]

It would. I also thought that the same could be done to layer groups.

Still, I would prefer to see data-defined properties for locking layer
(presets) in map items in the map composer. It would be much easier to pick
a few layers, create a few presets, and them "iterare" them in atlas.
