Keep the interface the same changing the user interface should not change the only thing that should change is the map updating not the interface if someone wants to see a quick overview the button should already be visible and easy to tap on most likely the person using the app is the driver having to stair at their phone and find buttons or click more than one button just to see the route as a whole quickly instead if of having to search and look for things you should also put up a notification pop up when you first open Waze if you are changing the interface tell us where they were moved to giving no information means having to search through the app and figure out where things went your a map app not an interface app I should be able to open the app put in the address and drive away knowing nothing will change and I can find the interface options in the same place every time no matter what day month or year it is
