I split my iPad screen and place the Bible on the left, a commentary on the right, and sync the resources. Prior to v3 if I wanted a different commentary (on the right side of the split) I would tap near the title bar, go to the library, and choose a new commentary. Now, I don't see any way to do this without clearing the split, replacing the Bible version with the new commentary, reopening the split, and bringing up the Bible again. What am I missing?
