It would be good if we could create text in 2 different styles (smaller or a different colour). We often sing songs in English but need the text translated in German (but that isn't sung) underlying each song line for those who don't understand English.

This would also be useful for call and response type songs, or for displaying liturgy, where a demarcation between the leader and the congregations voice parts is required.
Something standard like a subset of markdown or using HTML tags (, ) would be good.
