This is a minor thing.
currently Dorico allows for fanned beams to originate from 1 beam and be developed gradually into either 2 or 3 beams.
The score I am practice copying requires the beaming to begin with 2 beams that develop into 3 (see image):
So it would be nice (but not pressing) to have this option available.
Also I was wondering, why stop at 3 beams? why shan’t I be able to develop my beam into 4 or even 5 beams?
