Currently, the Step to next/previous is functionally the same when navigating Bible books when you choose either Chapter or Article. It would be really cool if either a new "Pericope" option could be added, or if the "Article" choice could map to Pericopes for resources where they exist (screenshots below if helpful). Right now, there's no way (that I'm aware of) to quickly jump from one pericope to the next, and the "Article" function just takes you to the next chapter like the Chapter choice does.
