Would be great if the player could support the expanded view.
That the dropdown often seen at the top left (“Watch in Apple Environment”). This makes the screen really big and, depending on environment, reflects the image in a see or in the clouds.
It’s a great immersive feature and implementation may be a low hanging fruit.
