I am not sure but it sounds like you want to be able to watch games.  That is covered in this news article.

Watch Top Players And Friends

You can still watch your friends and top players as they're playing games. You can do that by going to our Play Online page and navigating to the "Players" tab. You can then select the player you want to watch using any of the three available lists: "Friends," "All Players," and "Streaming."

Finding games by top players is also simple. Go to the "Games" tab on our Play Online page and select the "Watch" option. You'll see a list of players' games sorted by rating. You can click any game from that list to watch it live.

You can even watch more than one game simultaneously. Clicking multiple games will open them so you can keep track of as many games as you'd like. You can then navigate through them by going to the "Games" tab and selecting the "Open" option.
