The fact we can create groups of people in one single place makes our work easier as it helps us organize information about each person so they don't have any confusion when working together or communicating via email etc..
I wish there was more customization options such as adding pictures/profiles instead just text only profiles but this could be something added later if needed by customers since its free service from them. It has helped me keep track of my employees while also providing other benefits like helping out during emergencies (elevator breakdowns).
