As someone who has needed to test and debug existing regex code, this video was extremely helpful and not intimidating. Thank you!

At 28 mins there was a very brief moment where you walked through the example and drew boxes on the screen - however, the camera hides what is being explained. I mention it as I needed to pause and review a second time (as I didn't have the demo file loaded on another screen at that point). To be fair, the example is also visible in the video before and afterward.

I couldn't think of anyone I'd rather see making a comprehensive Regex video to simplify it and help us understand, thank you John!
