Is there a way to specify a feature of a shapefile or all features within a shapefile to serve as masking features for all other layers within a qgis project? I would like to crop all other features of other layers to the specified extent (hide everything that falls outside of the mask) without having to use geoprocessing tools. I know there is a mask plugin, but that does not allow to achieve what I try to achieve. This should work not just in print composer through the atlas.
It would be great to have that option within the layeer options or even the projects settings.
