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

42 \translator with no name and without assigning it to an
49 * fix singleStaffBracket
51 * repeat bars: need distance after ":|" and before "|:"
53 * The time signature warnings still remain, will be fixed later.

106 * zip target for binary windows dist (JBR)
108 * revise documentation
110 * junking \skip req in lyrics

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

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

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

323 TeX output to score-bar-scripts.tex...
328 * redhat (v?) graphical install bomb-out?
330 * GNU diff 2.7: diff -rN does not see a new directory with empty file
332 * GNU patch 2.1: <must find simple example> if patch chokes on a
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

474 - Move all Score_elems, into libmutype.a
478 - Doc (C) stuff of sheet music
479 - a better format? SGML? TeX? Info?
482 * more spanners (smallish)
486 * Rewrite Stem, Beam and Rhythmic_grouping (hairy)
488 - doc on Rhythmic_grouping
489 - general shaving on Beam and Stem
491 - separate visual from rhythmic info even more
493 - endbeam req should be *after* the duration, so you can do

500 - set different line sizes / thicknesses
501 - beam stem showthrough, inter beam sizes (french vs german style)

570 * adaptive accidental spacing.
572 * handle EOF graciously in error messages.
574 * centered whole rest
