I use the DevTools every day, I see other people using them every day, I see people in videos using them almost every day. They are pretty much ubiquitous across our industry, and yet - up until researching this article - they still held some dark corners I had not explored. So, as seems to be becoming my habit (if you've glanced over my previous articles) I've gone through the documentation and boiled it all down into a single post. If you're not already a DevTools pro I recommend opening another browser window beside this one and open DevTools to follow along - even for the sections you know and use every day, there might just be one tiny little extra thing that had escaped notice! At least that's what I found, and I hope you'll find those things too.
