About Interface Customization
ZBrush 3 introduces powerful new interface customization features. Any interface element may now be moved, even if that item does not exist when ZBrush launches. Additionally, entire new menus can be built to hold these elements, making it possible to redesign the ZBrush interface however you see fit. The Rapid UI is one example of what is possible, showing how the interface can be completely transformed to meet certain needs or tasks.
