Clients can easily create more than one Favorite List by clicking on the Favorite button (heart icon) at the top right corner of their Collection. If they are not already logged in to their Favorites with their email address, they will be asked to enter it.
Once they have logged in, they will see all of the existing Lists they have created as well as an option to Create a new List.
Clients will also see the option to Create a new List in the Gallery view when they click the heart icon on an image to Favorite it.
