Hi Luca,

of course theses layers are now twice in the layer tree. Once in the upper leaf derived from the qgs file and once in the lower "Background Layers" leaf. For user interaction I did some more scripting: If the user toggles visibility of the layer in the upper leaf this toggling is ignored and the corresponding layer is toggled in the lower leaf.

Hi,

this is the drawback of background layers. They are not layers in the
project.
What I do:
I load the same layers (given they are WMS layers) additionally into the
project (with the same name!) Thus these layers can be printed. To
ensure they are visible when the user clicks on printing I use the
following code (in Customizations.js, ATTENTION: work in progress):

Marvellous! But are they (the WMS background layers) visible in the
layerTree, too?
