@JakubBr This is a great idea and would be an easy solution to implement, since they already have all that space there.

I know this topic is a bit old, but the issue remains unresolved. You basically get stuck if a pinned tab is playing sound, which creates a confusing and poor user experience.

Maybe if the tab is pinned, and it's playing sound, Opera team can add a little extra room on the tab for the sound icon. We need enough room to select the tab without getting stuck in the mute/unmute loop.
