It would be good to be able to select as a personal, and maybe temporary,
preference another language (or rather locale) as the source for the second and
third coloumn data. Currently it is always "en_US" data that is shown. This
would make it a bit easier to get consistent data submissions for locales for
related languages (e.g. Swedish/Norwegian, Dutch/Afrikaans, and others). As a
translator one can then, e.g. easily look at Nynorsk data while filling in or
checking/vetting Norwegian Bokmål data, and many other similar cases where
consistency is a high priority.
