In ArcGIS I am used to being able to have a couple of MXD documents open and copy-paste groups of layers from one MXD's table of contents to another. This can save a LOT of time ensuring consistent styles, but also in setting up the drawing order, pulling in the data, defining its CRS etc. for the group
I would like to do the same thing in QGIS. I have two QGS documents open but there is no apparent option to save or copy a group of layers and dragging/dropping doesn't work (I get a little 'No Entry' symbol).
Is this possible and, if so, how?
