Thanks for your interest! I have not done much work on this extension recently, but you might want to check out Heb12 for desktop at https://github.com/heb12/heb12-desktop/ . It supports all those features you mentioned. The random verses simply uses a predetermined list. I know it is small, but I hope to use another tool I built to make them truly random.

As for the Bible translation, I would need to find another API that supports more. If you can find one that would be great! But for now that is not very possible due to the limitations of the Biblia API I am currently using.

I will do some more work on it in the coming weeks. :-)
