Add open in codesandbox button #3026

From what I understand, CodeSandbox is just an editor online (one of many). It seems that its use cases aren't that many/frequent to justify a button to it for everyone.

Why would you use CodeSandbox instead of your local editor? Does that happen often?

Some repositories require codesandbox example to be included before opening an issue.

I thought perhaps that might be useful.

Can you link to these repositories?

• https://github.com/react-hook-form/react-hook-form/blob/master/.github/ISSUE_TEMPLATE/bug_report.md

Also, I have seen some other repo's requesting reproducible example(codesandbox or any)

This is just a suggestion, if it doesn't seem required, feel free to close this issue.

There's a fundamental difference between the tweet and reproducible examples:

• If Refined GitHub adds a "Open in CodeSandbox" link, the sandbox will start with the repo's content.
• Reproducible examples do not start from the current repo, their content is actually something like require('current-repo-module') where you add your own broken code.
