Curious about why \once \override NoteColumn.force-hshift only seems to affect the first note of a measure. This snippet shows 3 staves, the first unmodified, the second with the chord shifted left and the e'' shifted right, and the third attempting to shift both e'' and c'' right. But the c'' is not affected by the NoteColumn.force-hshift directive.
This simplified snippet is from a working score where I'd very much like to shift that second note to the right.
