Diff Copier

This Chrome extension adds a "Copy as Markdown" button to GitHub Pull Request pages. Clicking this button, or pressing Cmd+C twice quickly (when no text is selected), fetches the diff content of the PR and copies it to the user's clipboard in Markdown format.

Warning: This extension fetches the PR content by accessing the .diff URL provided by GitHub. Frequent use, especially on large repositories or across many PRs in a short period, may lead to hitting GitHub's rate limits, resulting in temporary errors (like HTTP 429).
