I just hope that for Mac BIAB 2013 they clean up the interface. It's still a real pain that I can see measures 1-64, but if I jump ahead, I'm looking at 65-128. There's no way I can work with 8 or 16 bars in the middle of a song (say, measures 57-72), at the same time on the same screen. A long-standing issue, and frustrating enough that I still rely on the Windows version when I'm dealing with the overall structure of a song. Please, PG, fix this in BIAB 2013, and do whatever you can to make working with the product easier and more intuitive.
