The favourites tab allows you to save frequently used contacts in your own personal favourites tab, making it easy to find them.
Cloud Phonebook contacts can be easily added to your favourites tab by selecting the star by the side of the contact icon.
Your favourites will then appear in the list you created.
To remove a favourite, click on the name you want to remove from the list. Once it is shown on the screen on the right, unselect the star, and the favourite will be removed from the list the next time you view your favourites.
