Photon Friend List is a drag and drop allowing you to have in your photon multiplayer game features a friends list, and you want to know if a friend is online or offline, or perhaps even want to join your friend if they are playing in a room. Luckily Photon PUN has added easy support for this via the 'find friends' feature, which allows you to query the online states of a given list of users, as well the rooms the users are currently in if any.
