A little wish: If a real glissando is not possible, but the musician can fake something what sounds like glissando, I write “quasi gliss”. It would be nice to have this option also in Dorico!
I often think of things like this for the giant descending oboe glissando that Mahler writes sometimes. It’s not really a glissando!
I’m sure it’ll come when the team addresses lines, which hopefully will be soon-ish.
