DOES NOT WORK UNLESS DOCKED. Instantly started working perfectly when I docked it instead of having the dev console in separate window.
The Analyse button never even appear...
Doesn't work at all.
As noted by others, doesn't work.
Found this info in the a Github issue: "I managed to fix this problem by docking my chrome dev tools instead of using them in a separate window." HTH
To add a little more detail... Currently when I open Chrome Dev tools with the extension installed, I see a tab named 'Coach.' When I click it, I see a button 'Analyse' and another link in the form of a logo of a little bear that links to the github page. Clicking Analyse doesn't seem to do anything from what I can tell.
Definitely not working currently
I can't get it to do anything except take me back to the Chrome Extension page. Running the latest, 54.0.2840.71 m
