Sometimes Google Chrome will be playing audio through a tab, and if you're like me, you have 20+ tabs open at once. When this happens, it can be so hard to find it, but the latest Chrome beta stops that.
The latest beta of Chrome now shows a small speaker icon next to its name, which indicates that there is audio playing in the tab. This is a brilliant little addition, that helps a lot. But, the Mountain View-based giant aren't the first to do something like this, but a little addition like this does go a long way.
