Better Network Panel

This extension is Open Source:
https://github.com/leothelocust/better-network-chrome-panel

Although it doesn't do everything the default Network panel does, it does way more regarding Searching/Filtering. It doesn't only search the URL, it also searches every part of the request, including headers and post body.

Additionally, if a response is in JSON, and contains some stringified node in that response, this tool auto-parses that string.
