PR Elsewhere
PR Elsewhere is a Chrome extension that adds a View in menu to GitHub pull requests, and it's now on the Chrome Web Store.
I wanted an easy way to jump from a GitHub pull request to the other tools I view PRs in, so I made PR Elsewhere. It adds a “View in” menu next to the tabs on a PR page, and picking a provider opens the same PR there. For now the providers are Diffshub, pulls.review and Graphite.
It has a keyboard shortcut too. Press e on a PR page to open the menu, then press the number next to a provider. I picked e because GitHub and Refined GitHub already use most other single keys, and v opens the review dialog.
It’s on the Chrome Web Store (external site) and the source is on GitHub (external site). It also runs in Firefox, but only as a temporary add-on.
