I notice that in the latest release we have the pronunciation audible by pressing the enter button. However, that feature does not work if you are reading your Greek New Testament. The tool seems to be kind of "useless" if it does not work in your Bible.
My suggestion is to make that feature work in the Greek Bibles themselves. If you click on the word and hit enter it pronounces the Greek Lemma or Manuscript. Or if you select the word you automatically get an pronunciation. That seems to be the best way to use that feature. Not having to open another tool and then search to find the word and then hear a pronunciation of it. I know that you can right click on the word and click pronounce, but it seems that in light of this new feature, it would be better served to be used, in the same manner, within the Greek Bibles themselves.
