## What it shows

1. **Start with the page**: Reports lists the slowest URLs.
2. **The picture**: Merged over every slow run.
3. **Your code, or all frames**: Server frames are hidden by default.
4. **Where the time went**: The places that spent it.
5. **Ask Lensy**: It reads the picture and says what to change.
6. **Share it**: Your people, your channels, or any address.
7. **Watch this URL**: A rule that ends by itself.
8. **One request**: The slowest runs open their own page.
9. **Watch from a request**: Look at this URL the next time it runs.
10. **While it runs**: A button on a running request.
11. **The rules**: Which requests to look at.
12. **The switch and the limits**: Off until you switch it on.
