I found this list here:

  • Searching (display works) in Arabic, Chinese, Cyrillic, Korean, Japanese, Lithuanian, Slavonic, Thai, and Turkish Bibles. Searching and display issues with Czech, Polish, and Romanian Bibles.
  • Text-to-speech (Bible text read aloud)
  • Toolbar customization
  • Running BibleWorks from a Windows Server in a site license setup

It also refers to an old (2012) post here:

The last changes listed there appear to be from 2013-05-08. Is that still the current status? Any updates (improvements) since then? I'm trying to install the Mac app right now.
