Does what it's supposed to do :) very useful
Doesn't seem to work, no tab displayed in dev tools EDIT - working after a browser restart :-)
Installs easily, works well in Chrome. The info is detailed, a lot to unpack for someone who's not a dev. But it points out areas that need to be pared down, and at least gives me insight into which of my pages are too heavy on nodes.
