Hello Dorico team,
I hope you are doing well! 
Would be nice if you add the following E.Ms. assignable articulations for Plucked Strings (acoustic guitar, saz, tambura, oud, lute, mandolin):
- Trills up to Major 3rd
- Single note, or phrase extendable vibrato symbol (it looks similar to the Wiggly lines)
-
Here is an example of fingered (left hand) Vibrato and Wide Vibrato for acoustic guitar:
-
In the next example you will various Vibrato symbols (the wide ones are most noticeable on the fretless instruments) . They should also be included and available for E.Ms assignment:
-
Here is an example of combined narrow and wide Vibratos, so we should be able to combine them in Dorico, too:
More information can be found here:
Thank you very much in advance!
Best wishes,
Thurisaz
