In German songbooks chordnames are only displayed if they have changed. Lilypond shows chordnames at the beginning of a new line even if the chordname has not changed. Is it possible to change this behaviour?
I just have finished my document by typesetting using "lualatex". Up to now I did not find another solution to my problem by hiding some chords manually by using \once \override ChordNames.ChordName.color = #white.
Hope to find another solution, soon.
