This image shows the Designer with the App UIs pane open on the left. There is one App UI, sampleappui, and two dependencies, Very New Base Planets and Unified Application. Very New Base Planets is expanded, and we can see the contents of its App UI, smart and notsmart. The notsmart App UI has two pages in the main flow and the smart App UI has five pages in the main flow. This App UI is selected, thus showing all its pages in the Diagram tab to the right of the App UI pane.
