[QGIS-Developer] Offline layer

[matteo]

Hi Patrick,

mmm where?

https://qgis.org/pyqgis/master/search.html?q=isOfflineEditable&check_keywords=yes&area=default

I was wondering if there is a list of all the custom properties 
available for the layer, but I cannot find it. Also the 
QgsMapLayer.setCustomProperty does not explicitly list the keys available:

https://qgis.org/pyqgis/master/core/QgsMapLayer.html#qgis.core.QgsMapLayer.setCustomProperty

Cheers and thanks

Matteo
