Note-to-note lines don't avoid staff....

other lines do.

actually, it seems a lot of the line permutations (note-to-bar, etc.) don’t avoid the staff and actually don’t span the selected note/bar, whatever.

correctable in Engrave mode…

That seems like the correct behavior for a note-to-note (or -to-note or note-to-) line. If you want it connected to a note that’s in the staff, then the line is going to have to go through the staff.

Maybe you want a rhythmic grid line? Or do you expect the line to go up and over the other notes?

Note-to-note lines are meant to go from note head to note head, similar to a gliss line.

If you want something that spans other notes and avoids the staff, you want lines attached to rhythmic grid positions or a bar lines.
