[welcome]

💖 Thanks for opening this pull request! 💖

Here is a list of things that will help get it across the finish line:

• Run yarn lint locally to catch formatting errors. This will fix some errors automatically, commit and push any changes.
• Run yarn test locally to catch errors. This ensures all components still behave as they should.
• Run yarn start to run the doc site locally and try a few pages, ensuring everything is in good working order.
• Include tests when adding/changing behavior.

We get a lot of pull requests on this repo, so please be patient and we will get back to you as soon as we can.

Hey @layershifter!

We would love to hear your feedback on this PR. This is a customization we have been looking for for a while!

Thank you,

Let's not version the example titles in this way. It will be confusing with the semver already in place.

This is really fantastic, thanks for the great work. I'll get this merged and shipped.
