Glissandi are aligned horizontally and vertically to not collide with notes, note dots and/or accidentals.
Usually glissandi are note-attached smartshapes or tab slides.
By selecting "Handle Solid Lines as Glissando
" or "Handle Dashed Lines As Glissando
" it's also possible to use measure-attached smartshapes as glissandi.
As this option is unselected by default, it's not available in the Silver edition.
: If selected, the algorithm currently assumes that all
solid and/or dashed lines are glissandi. So use with caution.
Otherwise for example dashed crescendo lines might be turned into a vertical glissando line.
