I tried using Text Comparison to compare the Nestle-Aland Greek New Testament to the Byzantine/Majority Textform Greek New Testament. I set it to "ignore case", "ignore marks" and "ignore punctuation" otherwise it will mark every word as different because diacritical marks, such as accents and breathing marks, are not included in the Byzantine/Majority Textform as they are in the NA27. This generally works well, but in John 1:1 it considers the entire verse to be different, but I am not sure why.
What does the little red circle mean in the comparison?
I miss the version 3 comparison which shows additions and deletions compared to the base text in a different color.
