Is there a way to use a single map but turn layers on and off independently from the map TOC in different map frames and layouts?
This could allow us to update symbology on a single map which would in turn update many layouts. This would mean we do not need to update symbology for many maps. Currently it is only possible (as far as i am aware) to change the extent of a map frame in a layout that does snot affect the map itself.
I believe this is possible in QGIS by being able to lock the layers in print composer:
