Preference Option to Make Scroll Wheel's Main Function Zoom
Presently the mouse scroll wheel pans and you must hold alt + scroll wheel to zoom. I use zoom far more often than pan. It would be great if you could add the ability to change the default behavior to zoom somewhere in the preferences. This would speed up my workflow so much when using Illustrator!

James, you can do it in the latest release — Preferences, General: Zoom with the Mouse wheel.
Yep, this took them that much to add this.
