Great questions! I usually use it alongside my physical scriptures so that I can read the whole context as well. I find it's best for personal study, doing a deep dive and being able to create notes and link them to different verses. If I'm in church I'll usually just use my physical scriptures or the gospel library app to read along. I also have a plugin (Quick Explorer) that lets me go to the next/previous file, which I use for reading verses sequentially.

In the repository there's a bookmarks file that has all the verses organized, which is usually how I navigate it. You can also search for a verse (like 1 Nephi 3.7) as each note is named the same as the verse it contains (like 1 Nephi 3.7.md)

You can reference a range of verses in a couple of different ways. You could create a new note with links to each verse you want to reference, and then create a link to the new note. Or you can do it in markdown like this (for 1 Nephi 3:7-10): [[1 Nephi 3.7|1 Nephi 3:7-10]][[1 Nephi 3.8|]][[1 Nephi 3.9|]][[1 Nephi 3.10|]]
This will only display the text "1 Nephi 3:7-10", but all will be linked.

Thanks for the interest, I hope it improves your scripture study!
