Add "Export as PDF" menu bar item in macOS version
Mail.app has this, and it makes saving a message as a PDF much faster than selecting the Print menu then saving it as a PDF
I concur with Steven and fully support this idea. I believe the "export as pdf or print as pdf" button could be added under "Print" when one clicks arrow down in a single message or when one uses right mouse button for a thread. This feature would really help professionals who needs to export files as PDF.
Hope it will get implemented soon.
