Hello Dorico crew,
Would be really great if you think about possible collaboration with the guys behind Staffpad, in order to create similar communication
like the one between PhotoScore&NotateMe and Sibelius. To transfer, back and forth, easily and faster projects between both application,
also an option for Update/Refresh currently transferred projects would be nice. All without the need to export MusicXML, or MIDI.
That way Staffpad could serve not only as standalone notation software, but also a handwriting tool for Dorico. 
I hope you would think about this idea!
Best regards and Stay Safe,
Thurisaz
