Another suggestion to complete the App Builder is to add an event for a page setting to set a local storage value from a parameter (and another action to delete that value). In this way, when send someone to a page, we can append a parameter to page, save that parameter to local storage and then we have a sort of “state” we can use for other events in the app builder. This is crucial when interacting without outside APIs and for keeping some sort of state as the person is navigating the app builder.
