One of the downsides of having multiple windows with multiple tabs open is that sometimes one of those sites starting playing music/sound and you have no idea which one is responsilble.
Chrome, my browser of choice, has recently added a little speaker icon to any tab that is currently playing audio. This makes me so happy that I should probably take a good look at my life. A small, small feature which has made my browsing much, much better.
Thanks, Google. You’re still kinda creepy, but your Chrome team is doing good work!
