I noted that with the beta I have also acquired the Logos LXX. I was hoping to be able to search across both the LXX and the NA27 at the same time for a word rather than having to do separate searches for each area. In 3.0 I did this by switching to the NA27 with Gramcord morphology to match the morphology of the LXX which I have in 3.0. (I could then click on the reference for the NT and get the NA27 with Logos morphology since that is my preferred bible for NT while I had to click on the LXX It appears that this cannot be done in 4.0 since there is no provision for "All resources of the specified morphology." This would be a useful addition.
I also note that in searching the LXX for πέτρα in 4.0 I get 19 or 17 results depending on whether I choose Logos or Gramcord morphology (although it appears to be the identical list). Neither morphology displays the apocrypha when I choose "Bible and apocrypha." If I choose "Apocrypha" alone I get no results. In 3.0 I get 101 hits in 81 verses which does include the apocrypha.
