Online I use a site that gives me (verse by verse, unfortunately) the Septuagint (Greek), Hebrew and Latin (Vulgate) in a single pane. I would appreciate a single pane in which one could check the languages and/or Bible version you wished to see and simply see all the checked versions' text aligned at the verse level.
Side notes: This is how we were taught to work in Graduate School in a seminar where the text was available in 4-8 langauages of which you had to read 3 to be in the seminar.
