Hi.
I have a feature request...What could be called a "Switch" node. That is, a general node that you can connect any number of alternatives for a particular type (material, camera, meshes). It is kind of like a group node, but would allow you to do things like connect a bunch of unique materials to it, then decide which one you want to use by selecting a pin #. This would be a time saver for situations where you might have two entirely different materials that you want to be able to toggle between depending on the needs of a particular shot, but that are connected to numerous objects. So instead of, say, disconnecting one material 10 times from ten objects, by connecting another material for those ten objects, or going through the material to reset it for another texture, you can just change the pin# and it all gets done in one click:
