Observe multiple games at once

In a video by IM Rensch https://www.youtube.com/watch?v=67SQqsDnS-s we were told that we can observe as many games as they can fit onto our screens. This feature is enabled from the detach icon just below the settings on the top right of the game.

However, this feature has disappeared and we are most disappointed !!

Please give us back this feature.

I am looking for this feature as well. I can't find it. Will they bring it back? It's so useful if you want to watch multiple games. 

I watched the same video and am also searching for that icon (which does not exist to me).  Is this only available to those with the highest paid membership?

My guess is that it is something the site is testing and only available to staff.

I'm looking forward to this feature. I'm hoping to host and commentate a tournament with friends but looks like there's no way to watch multiple games at once on 1 screen. Flipping between games stored on the right side of the screen is a good solution but not ideal.
