very nice. there are things that won't show up in the network panel and you had to resort to proxy for debugging, especially when you are using puppeteer/etc for testing.

The absolute safest way to grab all traffic is capturing a netlog (https://www.chromium.org/developers/design-documents/network...) unfortunately there's been a lot of quirks with network captures through devtools and even with some of the recent bugfixes (https://issues.chromium.org/issues/40254754) they can still be lossy.
