Looks like MS has removed that feature - as far as I am concerned this is a big leaps backwards. There is a fix release (version 18.1) available. I have installed this but am experiencing problems dragging from the Object Explorer window to either a query window or to a database diagram.
As far as I am concerned version 18.1 is not useable and I am going to go back to an earlier version of SSMS
