1 Features you cannot find in the doco as working, should be mentioned here.
3 This is an assorted collection of stuff that will be done, might be
4 done, or is an idea that I want to think about
6 Most of the items are marked in the code as well, with full explanation.

42 \translator with no name and without assigning it to an
47 * \type Voice \times 2/3 { [c8 c16 c16 c16 c16] }
49 * fix singleStaffBracket
51 * repeat bars: need distance after ":|" and before "|:"

102 * strip EXEs before installing
104 * zip target for binary windows dist (JBR)
106 * revise documentation
108 * junking \skip req in lyrics

150 gs: Error: /undefined in draw_beam
153 * run texhash after installing .tex
155 * fix vertical alignment and stafflines
157 * GrandStaff needs more work -- I want a single word
158 `harpsichord' to the left of the grandstaff, not one on each
159 stave. (Organ staff -- with separate pedal -- but common
160 properties may be something to think about. Of course for
161 organ you want to be able to give stop indications on the way
162 through, so the \property Voice.Instrument would be a stop,
163 and \property GrandStaff.instrument would be PipeOrgan...)
165 * make Tie_req a "command" { <c g> ~ <c g> }

191 - NEWS: ... Musical_pitch (analogous to Duration and Rhythmic_req)
192 think about, analogous to pitch:
193 * { a4 a16 } c <-- duration of c?
194 * <a4 b8> c <-- duration of c?
198 * fix audio-items (don't use (input) requests, but copy data)
200 * junk My_lily_parser::abbrev_beam_type_i_

258 * disable spaces in TeX stuff
260 * handle ^C for tmp/file creation.
262 * dots & rest collisions.
270 * versioning for Feta
272 * the warning about the negative slur/tie length appears twice
275 * The `3' in the meter key is a one or two pixels too thin (at 600dpi)
278 * the bracket is ugly (wings are too parabolic, should be more circular)
280 * better hshift (dots, distance, head dependent)
282 * clefs (AG): The "8" should appear closer to the actual clef,
285 * put errorlevel in Input class
289 * integrate midi-elts from mi2mu and lily?

333 hunk, or on allegedly unsorted hunks in a diff, it may stop
334 without a trace of failure (create .rej file, print error or
335 dump core) and just ignore any further diffs.
339 f = fopen ("/dev/null", "r")

380 - bartypes (get rid of derived Span_bar_engravers)
385 - optimal pagebreaking.
387 * Unicode support? -> man 7 unicode
390 - detect of 16/8 bit files

472 - PostScript output (esp. Beams, Slurs, etc)
473 - Move all Score_elems, into libmutype.a
477 - Doc (C) stuff of sheet music
478 - a better format? SGML? TeX? Info?
