this is great !! And I was not a little but a big blockhead.;)

The arpeggio seems to belong to the NoteColumn (with "2.15.x"),
although the IR speaks only about Stems and NoteHeads . This means
that a chord with an arpeggio has a bigger extent (and length) and is
selected when passing the condition of dir-correction as being greater
than one-note-head-length.
It's of course possible to change the condition, but I'm not sure,
perhaps it's a bug. Did you notice
where I ask about it (so far without answer)?

Many, many thanks!!
