I am noticing a few issues with the "Corresponding text in other books" feature. (1) It is not showing in some resources where it used to be an option, and (2) it is not functioning as expected / as it used to, resulting in a lesser functionality.
First, the "Corresponding text in other books" option is not showing in one of the two modules for Holmes, Michael William. The Apostolic Fathers: Greek Texts and English Translations. Updated ed. Grand Rapids, MI: Baker Books, 1999 (LLS:APFTHHLMENG; 2009-10-27T21:35:54Z; APFTHHLMENG.logos4). The Corresponding text option is showing in Holmes' Greek Text module, but is no longer in Holmes' English Translation model (as used to be the case). The Corresponding text functionality also seems to be broken for the Holmes En module.
Second, I am using these Holmes modules alongside Brannan's Apostolic Fathers Greek and English. I often have the Greek and English for each text open in their own respective tabs, meaning that there are four tabs, two Greek tabs on the left half of my screen and two English tabs on the right half of my screen. At any given time, only two tabs are visible and the second En and Gk tabs are behing those that I am looking at. In previous versions of the app, I could highlight a portion of the text in Gk and have the equivalent Eng. text highlighted so that I can look right at it. After highlighting the Gk. text, I could also switch tabs to the second English text and the appropriate portion of that second English text would also be highlighted. Not so anymore (Because of the issue with Holmes' En, I have had to test this by highlighting Brannan's En text and looking at the corresponding Gk texts). Now when I highlight a portion of the Gk text, the Eng text in view is also highlighted (though, not if it's the Holmes Eng; see ¶ above) but when I switch to the second english tab, there is no corresponding highlight in that text. In fact, when switching to the second tab, the corresponding highlighting is initally there but then disappears. Previously, with all four of these tabs linked in the same link set, I could highlight any one of the texts, the other three texts would have highlights, and I could click between them at will to compare. This funcitonality no longer works.
