    app, NEWS: metadata export settings are now ON by default.
    
    After many discussions, it has been decided to export the metadata by
    default since it seems to be what many people would expect and they
    would consider they "lost" metadata (especially if they overwrite their
    original). I don't entirely agree since privacy (particularly if you are
    not aware of metadata and information they may contain) is also an issue
    but not many seem to agree with me.
    So here it is! All metadata now exported as a default!
