Hey @hazy rain 👋
I’ve opened 2 pull requests for the feature updates:

Language Toggle: https://github.com/priscillatrevizan/regex-generator/pull/28/

Theme Toggle: https://github.com/priscillatrevizan/regex-generator/pull/30/

Please review them when you get a chance. Also, kindly merge the Language Toggle PR first, then the Theme Toggle PR, as the latter depends on the former. Thanks! 😄
