[REQ] In main language screen, show original (EN) text along with the translations

[gh658804]

When clicking on a language, all translation strings appear in a single screen, grouped by Status. it would be nice if under or over each translation, the original (EN) text also existed. That way, one could just take a quick look in a single page and see if the quality of all translations is acceptable to him or it needs corrections. Some separators (lines or different background colors) would be nice in this case.
