Having come across some situation recently where this would be useful, I was wondering if it would become possible for the auxiliary note of a trill to be shown when the interval is a “Perfect 1st”. As it stands, when this interval is selected no auxiliary note is shown. Attaching some excerpts which demonstrate use of this.
@ViliRobert do you think it would be possible to show in greater detail your method here on the forum, so that it is documented for all to see, please?
