It would be great if the Concordance feature could run a full Concordance report for the AV (KJV 1611). This way we could research the findings of the Greek text that it uses.
This is beneficial for those that want a well rounded approach to scholarship being that different versions of the bible use different interlinears.
The Concordance tool already works will all resources you have in your library. (It sounds like what you are really asking for is a reverse interlinear for AV; please make that suggestion at https://suggestbooks.uservoice.com .)
