At my finger tips, I found:
maps, audio and videos sermons,chapter introductions. There are bookmarks that can be sorted not only by book but also by date. Also a really neat bold yellow verse highlighter that not only underlines the verses, but gives you Dr. MacArthurs clear exposition.
I love my MacArthur NKJ study bible, and am now able, with this app, to delve deeper; by having it and the ESV. They now have added an NASB version. Giving me the option to read myself or have the text read to me.
I have all the tools in this amazing app.
