Onion Circuits: please allow copying relay information

Hi! I need to grab the fingerprint of the exit node I’m using to connect to some machine, in order to reproduce a bug. It would be nice if I could select’n’copy this information only, but right-click → “Copy” on the node info block, that would copy the entire block, would be good too.
