We've been happy to hear that the media query bookmarklet has been helpful to so many of you media query loving web developers and designers. Over the course of the year there have been tweaks, but just this week, some helpful new additions have been made.
The bookmarklet no longer displays duplicate media queries, so you'll never see unnecessary duplicates on your screen. It also now has a close button to remove it and a control toggle to move the element from the right-hand to left-hand side of your display (in the event it is getting in your way).
