Oddly enough, this is the app that made me realize that Chrome puts a recording symbol next to the name of the page when a page is using your microphone now (kind of like when they put the speaker icon on tabs that are playing sound). I think that's pretty cool!

Edit: I should also mention that this is really well done, and I've been looking for something simple like this for a while. Thanks for sharing!

This is good, but what would be great is if I can click on that icon and silence the page. This would be useful to silence those ads that play a video automatically and don't provide a stop button

Personally I would hate clickable areas of a tab selector itself.

Like the X close button?
