I would like to suggest if there could be a sort of individual volume control and to where is putting out for each tab. Because i have a tv connected to the pc but also a party speaker connected, and having all tab only right here in opera, which is handy and useful, it could be a great difference. And also i would like to see it for the lateral bar, where there is whatsapp, facebook, instagram, twitter, discord. And also for the media player below with spotify, soundcloud and anything else.
