• Migrate old users to new subscription flow
• Refactor auth states (authenticating, authenticated, unauthenticated)
• Refactor chrome to look good while authorizing (possibly each component)
• Refactor entries to similar style as auth
• Refactor entries components to allow loading states
• Refactor settings to similar style as auth
• Refactor settings components to allow loading states
