-\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?
-
-. * 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.

+.* STUFF
+. * We need feta-din*.mf files for more sizes than 10.
+. * align left edge of broken (de)cresc/slur/tie/tuplet/volta
+. * fix dynamics decently, ie. use kerning & ligatures.
+. * key restorations & repeats
+. * paperXX.ly \quartwidth, font setting not up to date. (Should read from AFM?)
+. * * 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 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.
+. * 5. Sometimes lyrics extend past the right end of the staff. I guess that
+this is a similar problem (if not another symptom of the same problem) as
+one of the spacing bugs mentioned in the TODO.
+. * 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.
+. * decimal point in \paper {}
+. * tie-direction
+. * repeats and partial measures.
+. * rhythmic staff & accidentals.

- rftoe = \script { "ftoe" 0 0 1 0 0 }
-. * deps for ly2dvi
+. * collision of lyrics with span_bars. See star-spangled.
+. * Auto_beam debugging output (waarom/wanneer heb jij die weggehaald?)
+. * 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.

+. * 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.

touching it.
