Most of the items are marked in the code as well
-Grep for TODO and ugh/ugr/urg.

-.* BUGS
-. * sane strategy for extensions (assume .ly):
-02:22:24 appel ~/usr/src/lilypond$ lilypond foo
-GNU LilyPond 1.1.54.
-[/home/fred/usr/src/lilypond/scm/lily.scm]
-warning: can't find file: `init'
-. * indent = 0.0 with linewidth=-1.0
-. * music ending in grace notes.
-. * PostScript
-. * half notes in pfa
-. * didot / big point.
-. * check EGCS version
-. * input/test/stem-spacing.ly: 12/4 touches first note
-. * \shape 1st dim skipped?
-. * turn slope-damping on/off
-. * We need feta-din*.mf files for more sizes than 10.
-. * fix dynamics decently, ie. use kerning & ligatures.
-. * dots & rest collisions?
-. * behavior of "that the obvious solution
-\lyrics { foo1*4 __ _ }" is unintuitive.
-. * Lyrics and scripts collide.
-. * a note with a circle after it, meaning:
-
- note + circle = note + 1/4 of its length
-
- the circle is like a dot that's not filled in. for example, on
- page three, the c-sharp on the second line should be a quarter with
- a circle, not a quarter tied to a sixteenth. is this at all
- possible with lily?
-. * grace_align_item -> stackingdir = left, weird placement.
-. * grace before triplet, see standchen
-. * tuplets that are written as "number : note", for example
- "3 : [image of a half note here]". possible?
+Grep -i for TODO, FIXME and ugh/ugr/urg.
+
+.* TODO
+. * use hash tabs iso. alist_ for elt property?
+. * agressive type-checking for SCM stuff.
+. * use "staff-space" and "half-space" iso interline,
+ staff_line_leading () etc.
+. * why does Voice.beamQuantisation = #'none not work?
+ overriding in ly/params.ly works fine
+
+. * TODO^2:
+. * make a TODO.texi, like http://www.gnu.org/software/guile/ideas.html
+. * make this file understandable for 3rd parties.
+. * \accepts -> \acceptedby
+. * context in embedded SCM errors.
+. * eradicate all VIRTUAL_COPY_CONS () macros ; use indexed creation,
+ eg.
+
+ ctor_dict["Score_element"]->clone_func (orig);
+ ctor_dict["Score_element"]->create_func ();
+. * acc at tied note after linebreak.
+. * fix font-naming and selecting
+. * sparse ties.
+. * chord tonic: placement of accidental C#, Cb (from scm and C++)
+. * note head on stem err msg in dutch.
+. * why need to run -C mf twice?
+. * here's no difference at all in output. When either is jacked up to 7.0,
+everything works and matches up; when either is set just a bit above the
+default 5.0 (5.4 is what I was hoping to use), stems miss note heads. So
+it's some sort of a numerical (truncation/roundoff) problem.
+John
+. * fix #'margin-shape; setting indent to 0 with \shape fails
+. * Fixed size staff/system heights;
+. * ly2dvi : don't repeat opus if same.

+. * fix or replace feta-accordion.mf
+. * script engraver
+. * bracket pdf hack
+. * Mondrup:
+- if I change the property minVerticalAlign in a multi staff score with
+lyrics the change affects the lyrics too. I would like the change to
+_only_ affect staves.
+
+- I would like to be able to influence the sloping of xtuplet brackets
+
+- 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
+a"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 mensural music notation.
+
+- after the leading measure in the above mentioned score I want a double
+bar line fully drawn across the staves and after that keep to the
+ChoirStaff bar line types in the rest of the scores
+
+. * make all Feta (including dynamics) available to the user in
+ textual scripts. Examples: "D.S. al \coda", "\mf espress.".
+. * Write script that uses --find-old-relative to do auto relativization.
+. * Junk shared cruft (duration, moment) in lib/
-. * filenames : junk lily.x
-
-. * Matanya's tips:
-. * don't shorten stems/staffs closer to each other.
-. * accidentals closer to note head
-. * to space the staffs/staffgroups contained in the score.
-. * heavier beams?
.* Cleanups needed
-. * \$ and $ identifier syntax in examples.

+. * [c8. c16 c16 c16] in 6/8 timesig.
+. * Rewrite Stem, Beam (hairy)
+. * general shaving on Beam and Stem
+. * use plet grouping
+. * beams over bars
+. * Rests and beams don't work too well together. Example:
+ [ r8 g''16 des'] [r8 c16 a]
+. * autoBeamMelisma: if I explicitly beam notes in a staff with auto
+beaming disabled I would like to have these beams also to be
+melismatic.
+. * The stemLength property should affect also beamed stems.
+. * staffside spanner (crescendo!) along with staffswitch.

+.* STUFF
+. * We need feta-din*.mf files for more sizes than 10.
+. * align left edge of broken tuplet-spanner (have a test case?)
+. * fix dynamics decently, ie. use kerning & ligatures.
+. * key restorations & repeats
+. * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?)
+. *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 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.
+. * 4. Lyrics and grace sections don't go too well together.
+ The words are aligned with the main note, not the start of the
+ grace note. This is usually wrong, but is sometimes right.
+. * tie-direction
+. * repeats and partial measures.
+. * rhythmic staff & accidentals.
+. * use melismaBusy in Lyric context to typeset melismata correctly.
. * ly2dvi/lilypond logfile.
-. * fractional chord durs.

- rftoe = \script { "ftoe" 0 0 1 0 0 }
-. * deps for ly2dvi
+. * collision of lyrics with span_bars. See star-spangled.
+. * It is impossible to typeset two textual scripts that are stacked
+ 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
+ but the granularity is not fine enough, the scripts have to
+ share the same engraver in order to be get correct vertical
+ position but than they cannot have different style.
+ In my opinion, all scripts that share the same staff, should
+ be stacked vertically, avoiding collisions with the notes
+ in all voices.
-. * decide wether to junk _ in lyrics.
+. * Matanya's tips:
+. * don't shorten stems/staffs closer to each other.
+. * to space the staffs/staffgroups contained in the score.

+. * My wish list for lyrics. I dream of a time when I will have enough time to
become familiar enough with the source code to be able to implement some of
these myself, but I don't know when that will be, so I thought I'd "publish"
my suggestions in case someone else is in a position to give them some
beginning of each new line. This would make it easier to follow songs with a
large number of stanzas.
-2. Hyphens between syllables. At the moment there appears to be no easy way
-to position a hyphen mid-way between the syllables it breaks.
-
3. Notes centred above/below lyrics rather than left-aligned.
4. It would be very nice to be able to build some kind of phrasing into the
6. It would be nice to be able to put vertical brackets either side of a
repeated section with different words for each repeat.
