This plugin will show a new context menu item only on pull request pages. Right click on the page and click on ":octocat: Load all".
- Conversation tab → Shows all outdated comments
- Files changed tab → Loads all diffs
- Note: You may need to load all files into the view first by scrolling to the end of the page.
No problem, just c&p the code from index.js into the browser console and press enter.
