Good idea, thanks, but this completely prevents alignment of dots.
No no, dots in a chord, within one voice, are still aligned.
OK.
Remember that dots are not supposed to be aligned between separate
voices[1].
Interesting. However, if the dots' distances are not too far away
from the stem, the excellent Bärenreiter edition of the Bach Chaconne
*does* align them, even if they are in different voices. Note that
this is a manually engraved edition from 1959 or so.
LilyPond is wrong to align dots from different voices, but doing so
helps her handle the cases where note-heads collide between
opposite-stemmed voices.
If you are still working on the Bach Partita, then to my eyes
Dot_columns for each voice gives a *much* better result.
