That sounds like a useful idea. In fact, some earlier (as in prior to smartphones) scripture study applications had that type of feature. The old "The Scriptures" desktop application had capabilities to put multiple areas of scripture on screen at the same time so the student could read and compare other things. Being as this is a user-to-user forum, the likelihood is pretty small that your post will be seen by anyone with decision-making authority on the topic. In order to give your idea the best chance of being implemented, the feedback mechanism in the app would be the most effective.
Even more generally than scripture study, general-purpose computing adopted the concept allowing multiple things on the screen at the same time some decades ago. The Xerox Star system, the X Window System, the Amiga, Apple Lisa and Macintosh, and Microsoft Windows facilitated viewing several things on the screen at the same time. More recently, the small screen size of most cell phones seems to have migrated the usage model back to viewing only a single thing on the screen at a time. I find it interesting to watch the pattern of repetition in historical trends and such.
