This extension shows a visual notification when inactive tab plays sound.
This is a simple extension that is monitoring tab activity. When the tab state was changed to audible (i.e. when tab started to play sound), tab's window will be notified with "drawAttention: true", operating system will mark the window state as URGENT and the button in a task bar will start blinking.
- when there is a web chat client (e.g. whatsapp) and user wants to have visual notification in addition to sound notification,
- when some tab starts playing sound and user wants to find it quickly.
