I was thinking that being able to mute all tabs might be beneficial during times where you either are listening to music or can't risk sound playing through an ad that pops up while browsing. Any thoughts?
My opinion is there is enough very serious stuff that needs to be CONTINUED in Edge. When it looks like that is, actually, happening THEN, we could talk about adding things. I'm much more concerned about what seems to be missing, presently, than, any concerns about adding things.
As for this particular suggestion, myself, I'm having a hard time to imagine a scenario where there would be noise from more than 1 tab, simultaneously or often, that would need an All Off Mute button.
