JabRef 5.12
I might have overlooked it, but I do not find the rather central langid field in the entry editor. This field defines the principal language of the entry, which is important for hyphenation and whether (sentence) casing is applied. There is also langidopts for fine-tuning (with polyglossia)
The field is described in http://mirrors.ctan.org/macros/latex/contrib/biblatex/doc/biblatex.pdf at section 2.3.3
In my opinion, this should go to the "Optional" tab.
