Speaking of accidentals not correctly handled when using transposition:
the current implementation of figured bass in LilyPond is only
graphical (contrary to chords/chordmode).

It is possible to add accidentals to the figures with + ! -, but since
figuremode is not (currently) somehow "linked" to notes, these
accidentals are not correctly modified when the piece is transposed.

I do not see how one could do that, nor if this "feature" is really
asked/needed a lot, the amount of work or possible compatibility breaks,
hence before submitting a feature request to bug-lilypond, I would like
to know your thoughts about this.

Cheers,
Xavier
