Partial wish list of font character additions:
1) A flat and a sharp symbol made for imbedding in text instead of in music
that would have the proper base line and size for in-text usage. This would
be handy for text markup where you often need to specify these symbols,
currently you have to do a \raise and font adjustment to use "#" or "b"
symbols in text that flows.
(or possibly a generalized markup function that will automatically
resize/raise/lower any feta music character for use in a text context. for
example: "\asText \sharp" would render a sharp symbol baseline, height, etc.
as though it were an ordinary capital letter)
