pr+
A Chrome and Edge browser extension that adds a stack-aware pull request list and a fast in-page review modal to GitHub, so reviewers can browse, diff and comment on stacked PRs without leaving the pulls page.
pr+ is a browser extension for GitHub pull requests. On the pulls list, it reorders PRs into a base and head stack tree so stacked pull requests, where one PR's base is another PR's head, are visible at a glance, and clicking a PR opens a modal or side-sheet review shell instead of navigating to a new page. On an individual pull request page, it can replace the native PR body with the same shell, with an option to restore the standard GitHub UI.
The review shell covers the conversation, a virtualized diff view with syntax highlighting, leaving a review, line comments and suggestions, filters, subscribing, and merging, all without extra GitHub tab switches. Data loads progressively, from a cached list sketch to a live network refresh, and diffs and lists are cached in memory and IndexedDB with background revalidation.
It installs from the Chrome Web Store or as an unpacked extension.
