Today, the majority of softwares have a simply rule regarding using a mouse: scroll wheel to zoom in/out and middle button and pan with middle button clicked.
Simply like that.
So why only PS has the option to use the scroll wheel as zoom and the other softwares from the Adobe CC don't?
And why all the softwares in the Adobe CC doesn't the option to use the scroll wheel to zoom without pressing Alt and pan without the need to use the Spacebar.
If those features are implemented, most people that already use Adobe products will love it!
