The default bible seems to be "king james version 2000". So it should be kjv with modernized words, but no other changes. They also have the World English Bible which I use a lot. It appears all their translations are either Received Text or Byzantine/Majority Text based.
Edit: The term "catena bible" apparently refers to an arrangement of commentaries. In the settings I see they have commentaries from early church fathers, eastern church fathers, and western church fathers. But so far I don't see how to display the commentary information.
Ok, solved that. Just click on a verse and commentaries on that verse are shown in a window on the right.
I find it strange that the site doesn't seem to have an about page or explanations. It does appear to be useful. There are apps for apple and android devices; maybe those include descriptive information. It seems this was prepared for those who know exactly what a catena bible is. Yours truly not among them, I had never heard of such a thing until now.
