The overview of departments, locations, and areas in settings could be more efficient. It would be helpful to see which areas are linked to a location when selecting a location, and to have a search option for areas within that location. Similarly, being able to list and search for locations within a department would give a better overview.
An idea is to combine departments, locations, and areas into a single, unified view with a hierarchical structure. Departments will appear at the top level, with locations displayed underneath, and areas displayed within each location. Users can be able to click into a department to view its locations, or into a location to see its linked areas. A search function within each level will make it easy to quickly find specific locations or areas.
