This week, a new beta feature – Quick Transitions – will be available to all applications on Facebook, according to the Platform team.
The feature is designed to enhance both FBML and iframe application performance by making canvas page load times faster. To test the feature out, click on “Edit Settings” and find the Canvas tab. You’ll see the option of turning Quick Transitions on at the very bottom of the page.
You can find more details on implementing the feature at the Facebook Developers Wiki, including a couple tips for IFrame apps. If all goes well, the feature will enable applications to provide users with a friendlier user experience – faster apps!
