The thing about 8.5 and all previous versions was, the end user had the option to have as many or as few buttons as he wanted in the tool bar. It was 100% customizable and it was only cluttered by your own doing. I'm not really seeing how the X Series has improved upon this. It's never good to take away functionality, especially when it's been part of your software from day 1.
I think the popularity of Panup's mod speaks volumes over this blunder ... and a few others that he fixed.
I still can't believe they took the 'Phase' and 'Interleave' button off the tracks.
