I wanted to be able to close Chrome, and reopen my tab groups easily without opening every single tab. So I decided to try building a simple Chrome extension to do this. It's worked well for my use-case and is available on the Chrome store.
Granted, Chrome has since come out with their out native implementation of this, quite the timing I must say. 😆 So I don't imagine there's a need for this extension anymore! Still a fun learning experience.
