Going to github: thr ‘roadmap’ link 404s. Two Qs: 1) Do you plan on adding Google Re2 syntax and others 2) Is reversing available/planned? (reading written regex being notoriously more frustrating than writing it :)

I found a great list here.

• RegExr

  RegExr is a HTML/JS based tool for creating, testing, and learning about Regular Expressions.

Also, for your playground to be of value it should have a place where you can input text and have the portion of the text that got matched highlighted. A place where you could also put a replacement expression and see the result of the replace would be nice, but less critical. The interface of https://regexr.com/ would be a great starting point for a more functional playground.
