Woohoo! CTRL + drag to copy is nice; would it be possible to have it also copy the connections when used? :)
Currently it copies connections between nodes that are duplicated, so if you select both node and nodes that are connected to it and than CTRL+drag it, it should work... but we should probably add some command/shortcut to select node including its hierarchy to make this easier...
So it does, cool! Also cool is the bounding box select, nice!
On whether it should copy existing connections or not, I guess one for the users to chime in on; I'm just kinda used to it that way from Max, but not to say that it has to be done that way, especially with this functionality of "copy all nodes and connections from what was selected" (as that is something Max doesn't give you an option for, and I can see that being useful where you are already planning on changing some aspects of the new material).
