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

-
-[-> leading are the lead strips between the sticks (lines) of

-. * Rewrite \rhythm to be during interpreting.

-. * junk delayed spanner breaking.

-So how do I do what I want to do?
+There's insufficient leading between lines of lyrics, so risers like

+
+Also the lines are unevenly spaced.
+
+. * write comments in the source code
+. * internationalize GUILE msgs.
+. * roy rankin:
+1> The volta brackets are on top of the lyrics. This problem existed in
+ 1.2.x which I corrected by giving the brackets a vertical size. I
+ have not had the time to check what is going on in 1.3.
+
+2> Part names are being written on top of the staff and not in the
+ left margin.
+
+3> The tag at the end is spaced out clear across the page. (new problem
+ in 1.3.27)

+indicated by, e.g., one or more thick lines through the stem of a note

-> Would it be hard to add support for proper dynamics in MIDI output? I
-> would really like to have this feature...
-
-Concretely spoken, for dynamics you have to write a performer
-(Dynamics_performer), that will take the input requests. If I
-understand correctly, every MIDI note played must have its dynamic
-strength set separately. That means the the Dynamics_performer must
-set the strength of every Audio_note it finds. This means that one
-has to modify existing Audio items. The best way of doing this is
-with a broadcast/acknowledge process.
-
-So the best way of handling this, is
-
- 1 supporting dynamic settings in Audio_note
-
- 2 Write a Dynamics_performer that will modify
- any notes it finds to set appropriate strengths.
-
-I'd say that the work involved is not hard, but you have to be fluent
-with C++ and need some insight into the working of Notation Contexts
-and friends. I guess I could do it in a day or so, but if you are not
-so fluent with the inner workings of LilyPond, it could take you some
-more time (A few more days?).
-
-Please note, that I am *not* going to code this myself: my days are
-valuable, and I think I have more interesting things to do than fixing
-the MIDI output (I don't even have a soundcard). But I *do* want to help
-you or other people with implementing this, so if you need help, don't
-hesitate to ask.
