Using UIs
In the above image you see the UI pane. You cannot create a new UI; you'll have to descend it from one of the existing UI's. For instance if you want to create an UI for the customer's name, you double-click String at the left pane. That will bring the String UI at the right pane. Then you drag and drop from the string UI to a few centimeters below it. Enter the new UI's name and now you have a new UI, descended from String.
