Yes. The Extend Last System option can still leave absurdly long final bars. I haven't had a chance to try the suggested way yet, but I'm hoping it won't do that.
I have just upgraded to noteworthy 2.5 after using earlier versions for a good while. Can somebody tell me if there is now a simpler way of justifying the staff lengths so that a printed piece will always have the final bar to the right of the page? I have always had to fiddle with font/staff and margin sizes to achieve this. I can see that the use of the spacer tool could also be used, but this will also just introduce another permutation. Maybe I'm missing something obvious?
