In the new version they vastly improved the zoom with mouse wheel feature.
I had problems with customizing the quick access buttons but it seems to be working now. What I did was to customize the quick access buttons for the model view and saved it as My Theme. Then I went and customized the sheet view quick access buttons and when I save that I lost my customization for the model view so I had to redo those buttons. Also, the program crashed once while customizing the buttons. I allowed the program to send a report so hopefully that will be useful in finding out why it crashed.
