Navigation Bar 

Navigation bar implementation wired in. Interacts properly with the progress bar now so that it can be enabled/disabled and takes the place of the progress bar when enabled.
are you referring to the compareto specifically? Compare to definitely shouldn't. I'm not 100% sure that I ensured that my algorithm does the same thing with your new code though. Is it just JumpToNext and JumpToPrevious that need the "don't expand" flag?
