Thank you for the feedback. The app currently only provides a list of countries. If you click the arrow next to "Location List", it will display the list of countries. You can then select one, which will direct you to that country's location and display its name along with its latitude and longitude. The future plan is to add another list of cities and other specific areas, which will appear after you select a country and are viewing that country's location.
Regarding your suggestion to display the name of the country and city after entering the latitude and longitude, or after clicking a specific spot on the map, this will be considered for a future update of the app. The update will involve adding another layer on top of the map to show the country borders, as well as the names of countries and cities surrounding the selected location or spot.
