You can navigate through the rest of FormMaker using the tabs at the top, which include Page Structure, Field Details and Data Bindings.
An application in FormMaker refers to a collection of interconnected web pages and server-side Controllers that form a Web Application. The Application Map tab shows the overall structure and flow of the web applications, including the links between the pages and server controllers.
