Example
Examples of extensions:
- View messages between web-workers, service workers, and iframes.

Motivation
I love the Playwright Trace Viewer, it has been so useful for debugging problems locally and in CI/CD. To extend debugging capabilities, custom extension panels would make the tool much more powerful.
