## Description

Show-HTTP-Headers is a handy Chrome extension that displays HTTP headers for each tab. It organizes HTTP headers as a clear list for every HTTP request. Users can simply click any header item to copy its name and value directly to the clipboard, streamlining web debugging and inspection. The extension offers flexible options to include or exclude headers from all requests, all responses, and those matching specified URL patterns via regex or substring matching. URL patterns starting with the '^' character are treated as regular expressions, providing powerful filtering capabilities. This tool is ideal for developers, network analysts, and anyone interested in inspecting HTTP traffic within their browser.

With Show-HTTP-Headers, reviewing and managing HTTP headers becomes straightforward and efficient, enhancing productivity and simplifying network diagnostics.
