I am fine with criticism.
As time goes by many serious web developers surround themselves with tools to help them with their task. There are a myriad of them available to do something simple or some fancy stuff. The best thing about most of those tools is they are free; yes free no cost, zilch.
Because this tool is so popular (and of course free) it is now incorporated within all browsers and you thought it could not get any better.
So next time you use your browser hunt around for sumpin that looks like developer tools.
I am not going to test how well you can take criticism at this time but let you be wowed by the developers tools in your browser.
