Yes, this is also a way...
but i say it again - I mean selecting something inside the graph (a node) or more nodes by "drag-select-square" -> right-click on "free space"-> export (takes whatever format and path, that is set in the main-export-dialog)
So there should be no nees to go over to the Explorer window or to click the gear-icon...
I think this should be easy to do for the devs and would make for a nicer flow...
Cheers!
