Following your favourite players is easy. All player perspectives are located on the sides of the media player or under the button "Select stream" if you are on a smaller screen. Simply drag and drop whatever stream you are interested in into the media player and it will start to stream that specific point of view.
If you want to get fancy you can watch several point of views simultaneously by splitting the media player in up to four views. Choose your layout from the four options beneath the media player or in the bottom right corner of the media player.
