The K4 NT does have the progress bar. Maybe I just need more experience using it as a gauge, it gives me a rough idea but I used the method mentioned above for a more exact solution. I like to try ending on a new chapter if possible. Its one of those "its midnight and I'm tired but I wanna keep reading but should I?" things.
So I take it there is no other short-cut or quicker way?
Yeah, the tranny is my Transformer. I realize now some people might find that nickname offensive or derogatory and I won't use it anymore. Apologies if I offended anyone, it was purely unintentional. In my defense, I'm just not that bright!
