• display fingerprints in languages considered preferred by the user
• add link "more languages"/"fewer languages"

e.g.
primary language = de
fallback chain = de, en, fr

primary = fingerprint of de (i.e. based on a property of the user)
more languages = fingerprints of languages en, fr (i.e. based on a property of the user, all are shown even if not part of the entity)
all languages = fingerprints of all languages excluding de, en, fr (i.e. based on the languages already part of the entity; only those are shown)
