Typically, versions of a given article in different languages vary in detail. It is no longer the case that the English version is the
canonical, or the most detailed one.
For us multilingual readers, it would be handy to have an option to sort the language pane for a given article by some metric of
detail, for example word count or character count (depending on the language).
Another possibility is to give a list of, say, the three longest versions, at the bottom of the language list.
