Focus Diff von Hyan Mandian

Big pull requests mix the code you own with tests, docs, lock files and generated files. Focus Diff adds a small bar to the Files changed page so you can review one part at a time.

Filter the diff
• Make filters from file patterns: Frontend, Backend, Tests, Docs, or anything your repository needs.
• Start from ready-made examples, then keep filters for every repository or only one.
• Pick a filter and the diff shows only its files. Files changed and the +/− lines count only what you review.
• Share your filters with your team: copy them in settings, and a teammate imports them in theirs.

See what’s left
• Files left to review, lines added and removed, and an estimate of the review time, for the filter you’re on.
• A breakdown of every filter side by side.
• A Done badge when a filter is fully reviewed.

Move faster
• Jump to the next file you haven’t viewed (Alt+Shift+J).
• Step through every conversation on the pull request without scrolling for it.
• Switch filters from the keyboard: Alt+Shift+. and Alt+Shift+, to cycle, Alt+Shift+0 for all files. You can change every shortcut in your browser’s shortcut settings.

Private by design
• No account, no tracking, no network requests. Focus Diff reads the file paths and line counts already on the page, and nothing leaves your browser.
• Your filters and themes stay in your browser’s storage.

Works with the keyboard and screen readers, follows GitHub’s light and dark themes, and comes in English and Brazilian Portuguese. You can also make a theme of your own: pick the bar’s colours in settings with a live preview, and share it with your team.
