Displays media query events for the current page
A simple chrome extension to live display the current Media Query in use on a page. All found Media Queries are also logged to the console.

Doesn't work as expected, shows a red dot on bottom left :(
Only shows the current breakpoint when you increase the size of the window. When you decrease the size of the window it doesn't show the viewport that your currently in until you decrease the page enough to pass another breakpoint.
Love Mixture and a fan of it. Also Neil Kinnish is best at support. Thanks for the extension.
Awesome
Simple but very, very handy!
Simple and very useful! I used to rely on a window resizer extension to figure out which media queries are being applied, but now MQ Debug is all I need!
