The eye symbol next to the colour associated with each service category can be pressed to temporarily remove that category from the map. This function may make it easier to locate a specific point of interest since the map can appear to be overwhelming when all locations are displayed at once.
The magnifying glass to the right of the eye can be pressed to automatically zoom the screen so that all the mapped services of this category can be visualized. This is especially useful to find services which may be offered further from the city center.
