Tool to help you easily switch between your open PRs (or PRs you were asked to review).
Run
npm i git-list-prs
Then in your repo run git config github.apiKey <YOUR_GITHUB_API_KEY> (you can get GH api key from GitHub settings page).
Run git list-prs to list your open PRs or git list-prs -r to list open PRs you're assigned as a reviewer to.
Selecting from the list will checkout the PR branch. If you're running with -r it will also fetch the branch from remote origin and will try to do a fast-forward merge to ensure you're on the most recent commit.
