The Chrome Web Store rounds user counts down to the leading digit, so the user line moves in steps. The ratings count is exact and is the better signal of real adoption.

About GitHub Diff Helper: Go to Definition

Reviewing a pull request on GitHub, you constantly hit a function or class you don't recognize — but the diff only shows the changed lines, not where things are defined. GitHub's code navigation works on file views, but not inside PR diffs. GitHub Diff Helper fixes that. While reviewing a PR diff: • Double-click an identifier (or press Ctrl/Cmd+Shift+Y, or Alt-click it). • A small popover shows where it's defined, with a "Jump to definition" action. • If it's defined in the PR, it scrolls to and highlights the definition line. • If it's defined elsewhere in the repo, it falls back to GitHub code search — using your existing login, so private and organization repos work too. 100% client-side: • No backend server. • No GitHub token or extra login — it reuses your existing GitHub session. • No analytics, no tracking, and nothing leaves your browser. Network access is locked to github.com by the extension's content security policy. Supports definition detection across Kotlin, Java, JavaScript/TypeScript, Python, Go, and more.
