I have to say while I have been impressed with the overall layout and many of the "bells and whistles" of Logos 4, I have been somewhat disappointed in some of the basics that seem to have been lost in translation of Logos 3 to 4
My latest issue seems to be with the lack of many Hebrew and Greek words in the Word Study section of Logos 4 that seemed to have simply disappeared from vs. 3. For example I can find the word εἶπον (say) but not εἶπεν (speak). In other cases it appears I can only find certain forms of a word but not others such as being able to find αὐτός but not αὐτόν.
Other frustrations include weird buggy items like cutting and pasting the word κἂν or καὶ in the word search box will produce a drop down list with several other words with my word fourth or fifth in the list, even though it's the exact same word I cut and pasted! Why isn't it first? The problem is if you cut paste and hit enter like the old days of Logos 3, it will give you a completely different selection, choosing the one first in the list instead of your word and sending you off in the completely wrong direction. I then go back and hunt down the drop down list for my word.
I was hoping for a full upgrade, now I find myself switching back and forth between Logos 3 and Logos 4 to get the old Bible Word Study features. It's rather disappointing. If I am missing something here please let me know, I would love to get this working properly.
Words that Logos 4 does not identify from just two verses that can all easily be found in Logos 3:
John 11: 14: αὐτοῖς ἀπέθανεν
John 11:15 διʼ ὑμᾶς πιστεύσητε οὐκ ἤμην ἄγωμεν αὐτόν
