.MARKDOWN - Next.js/Redux/RegExp/MongoDB/MUI

I decided to make this even more of a challenge by building the Markdown generator myself using RegExp instead of a third party package. This one took me almost a month, and was by far the most challenging project I've tackled, but a lot of fun!

Things I'd love to get feedback on:

• RegExp
• The matching functionality - If you think there's room for improvement, any big "gotchas" you may notice
• The integration with the editor - Any bugs you may notice
• Any UI issues you may notice or areas to improve
• The authentication/login/logout functionality
• The CRUD functionality - especially when logged in and interacting with the database
