+- for one of my test scores containing a modern edition of an early
+17'th century composition I have a leading measure containing the
+orginal clefs and note values of the original composition. I use the
+"harmonic" and "diamond" note head styles for that measure and would
+like to have the stems of these notes _centered_ on the notehead as in

+- The syntax for chords looks clumsy with two different meanings of
+ '-' and different syntax for separating modifiers from the tonic
+ and from other modifiers. Why not use for example ':' between
+ tonic and modifier and between the different modifiers?

+- Rests and beams don't work too well together. Example:

+. * * auto melismaBusy for beams.
+. *In Caro Mio Ben, bar 8, there's a syllable that starts on a note, and
ends on a pair of grace notes. Standard practice is to mark this with
a slur starting on the main note and ending on the grace note, so a
singer knows where to break the words.
-In bar 26, there's a \p marker that should appear below the grace
-note.
-
In bar 27, there's a crescendo that's supposed to start at the start
of the grace notes and extend to the note after the grace notes.
-
-How do I specify these?
-
-How can I control whether a grace note takes its time from the note
-before or the note after it (for the purposes of alignment with
-lyrics)?
-. * / distance after 4/4 \key.
-. * spanners from grace to normal ctxt
-. * Glen:
-1. I got a vertical line where I asked for a decrescendo.
-
-2. Slurs -- good to see some spacing between slurs and lyrics, but not
-there's several times too much space.
-
-3. Slurs with wrong slopes. Where a slur between two notes goes from the
-head of one to the stem of another it can have the wrong slope:
- | ___
- | / \
- | / |
- x|/ |
- |
- x|
- The music goes down but the slur goes up (or vice versa). This looks
-wrong.
-
-4. Lyrics and \fermata collide. I know that the TODO has lyrics and scripts
-colliding; I'm just including it here because it's really an issue for me
-with fermata. Other scripts aren't a problem for me, but sometimes I need
-fermata on both sides of the staff (when sop and alto hold different notes,
-for example). In fact it's not just scripts and lyrics: In a choirstaff,
-scripts above the bass clef collide with scripts below the treble clef.

this is a similar problem (if not another symptom of the same problem) as
one of the spacing bugs mentioned in the TODO.
-
-6. The bar line at the beginning of an \alternative section has disappeared
-altogether.
-
-7. When it's a tight fit to get all the notes in the first line, the first
-note collides with the time signature. Is this the same as one of the
-spacing bugs mentioned in the TODO?

on top of eachother and avoids note collisions and at the same
time are typeset with different textStyle. I tried to move around
the text_engraver and other engravers between Voice and Thread
be stacked vertically, avoiding collisions with the notes
in all voices.
