** Description
It would be nice to have a "play all" button that queued all the videos on your subscription feed so you dont have to close the video and go back to pick a new one again.

Can this be made optional?

Users with large subscription feeds (dozens of channels) are not likely to want to play their entire feed like a playlist.
So this full width button becomes clutter.
