It would be great to be able to set 2nd reference language to be visible when doing translations. E.g. When the translator is translating Spanish, it's useful to see both English and French text, as English is often inconclusive, because you don't have conjugation and many other grammar structures there which other languages do.

I think it's quite useful to be able to see two languages to cross check terms etc, which en ables the translator to avoid mistakes or misunderstanding of the original term.
