The project is still in early development and to achieve the release of v1.0.0 here's what has to be done:

• UI
  • Better styling
• Backup
  • Support for encrypted backups
• Restore
  • Check if file is genuine backup or manually crafted file
  • Decryption for encrypted backup
  • Restore tabs & tab groups
  • Restore Bookmarks
  • Restore Extensions
• Ship it to the chrome extension store!
