User Interface Extensibility in Visio 2010
Learn about RibbonX, a XML markup that allows developers to customize the Office UI. It enables 3rd party developers and solution providers to build custom tabs and groups on top of the Ribbon, and target scenarios unique to and optimized for their customers. As Visio adopts the Fluent UI, Visio developers now also have the opportunity to utilize this platform to build and customize Fluent UI to offer users a more discoverable and instructive UI experience.
