Having another full Bible panel, or multiple Bible panels is not possible. However, you can get three Bibles showing at once by exporting and chapter to the MultiWindow. Actually, that is what I do over the Dual View. When exported to the MW the page is save in History and can be brought back up at any time. A whole MW session can be saved and reloaded. The exported pages will not be synced, but when you change a chapter just click the tab of the Bible you want to export, export it, and then click the tab back to the original Bible. Can be done very quickly.
The MW is quite powerful. See this video for some of its features, https://www.youtube.com/watch?v=oQweysHvqP0
To view synced Bible text the Parallel tab is best. At the top of the page click the Select Texts link to show only the Bible texts you want. You can display as many as you want.
