I have a QGIS project with a large number of layers. Is it (without using Postgis) possible to define "Views" which include different subsets of the layers? For example: View 1: Layers WMS topographic, roads and villages View 2: Blank background with only village outlines and existing sewer systems etc. This would come in handy because I have a number of print composers which are based on different selections of the layers. If I want to make a change to one of the print composers I have to remember which layers were visible when I locked the layers in the print composer.
