If you tap on the settings/cog icon on a video, there’s an item for “additional settled”, which then has another item for playback controls or something.

Once you want to do anything else you have to exit everything and open it back up though, it’s not really efficient

You rock! Thanks.

Desktop only feature. Have to enable it. It puts a sidebox with a mini remote where suggested videos usually are.

It's under "Modify Playback with Premium Controls":

> Desktop only feature

Weird, that page says "Premium controls are available on Android, iPhone, and tablets, but are not yet available on desktop.", and I'm not seeing the option on desktop

Whoops, I don't actually use them so I may have flipped it in my mind.
