When duplicating a layout, it would come in very handy if Dorico could also duplicate its printing information.
I often use this to create parts with transposition overrides, so all of the settings in Print Mode would need to be transferred, as I need them do be exactly the same.
(Of course there will be use cases for other users where the duplicated layout will need some other settings, but I think the settings of the current layout might be a better starting point than some arbitrary defaults.)
