Page Analyzer

First time I try this addons, I think it is nothing special, but after going deeper, now I know this addons have all that Google Chrome doesn't. Very smooth, Perfect.

No idea if it's Page Analyzer or Edge that's freezing. But brings the browser to stall yet nothing being reported via task manager on CPU usage.

It gives me a list of categories that the website follows standard or not, or if there's any missing part that should will be helpful (for example icon specific platform). Will definitely give 5 stars if it includes more in the list and more explanation including more examples.
