Custom Tabs On Facebook. For this I have created a Google App engine project. Page tabs will only be displayed in the web UI.
In the upper right hand corner of the Woobox homepage, click 'Sign up'. Page owners can add cover photos and they can also highlight important stories by pinning them to the top. Other than being able to create custom templates, additional value comes in the ability to organize your apps within this very easy to use interface.
Content of each page depends on the user who added the tab.
These custom Page tabs load content from your webserver using an iframe.
Open a new tab in your browser and navigate to Woobox. Page tabs will only be displayed in the web UI. If you want anything more, there are a variety of paid accounts to choose from.
