I guess I need more information on why you need two songs open at once, and you don't want to use a setlist. As a side note, you can load one song, then through the setlist window, add a second song to the current temporary setlist, essentially allowing you to flip between both songs.

If you use optimized PDFs, you should be able to switch between songs and have them load very, very quickly, so buffering the pages isn't as critical.
