I believe adding the Mishnah, Tosefta, Talmud, and Midrash in Hebrew/Aramaic would be GREAT additions now that all but the Tosefta have been added. (Preferably with vowel and cantillation markings). I know Accordance has at least the Mishnah in Hebrew with and without the vowels AND with variant texts. I think having the Mishnah, Talmud, Tosefta, and Midrash in Hebrew/Aramaic with vowels and variant texts (if available) would bring Logos MUCH closer to Accordance in competition (since Accordance STILL has things Logos doesn’t, such as a New English Translation of the Septuagint). I am sure these suggestions have been made already, but I am bringing them up...AGAIN.
(If you know the links to the original suggestions, please link here too).
