The question about LXX Englishman's search got me thinking about what I'd really like in a search - pie in the sky style and make mine blue huckleberries please.

What I would like to be able to do is
(1) Select English translation under consideration
(2) Select the languages used (Aramaic Targums, Syriac Peshitta, Amharic in addition to those shown above).
(3) Select manuscript(s) used for each language [not shown in picture]
(4) Select sequence of Biblical books
(5) Process would (a) find all lemmas translated into the English word for in this particular translations (b) find all occurences of those lemmas in the 'original' languages (c) sort the results into biblical book order within English translation lemma - putting those that match the originally selected word at the beginning
(6) Be able to open and close branches of the results to narrow down to what is of specific interest (basic Warnier-Orr or Brackets diagram functionality)
(7) Mouse over provides popup window with larger context
(8) Clicking on one of the English lemmas moves that lemma to the root and the diagram is rebuilt.
I recognize that this is not a "quick and dirty" add-in but it would be extremely powerful and done right could really make Logos standout from the competition.
