Maybe I'm tripping, but couldn't we alter the order of the buttons under the video preview on the toolbar before? Did I imagine that? I also think it would still be nice to have an option for those of us with less than perfect eyesight to have the buttons on all the toolbars able to be bigger. I know I had requested that in 15 as well. Just a basic "large icons" option and more space between then so I'm not always hitting the wrong ones...
Additionally since I have never used the "Rate" box in the bottom left of the UI it would be nice if that could be hidden like the other things like Master Bus.
