If these things appeal to you and you haven’t already looked at it, the GitHub CLI tool gh is very useful. For instance:

    gh repo clone MrLesk/Backlog.md
    cd Backlog.md
    gh issue view 140
    gh issue view 140 --json body --template "{{.body}}"

You can do things like fork repos, open pull requests from your current branch, etc.
