● You're absolutely correct! The backend functionality is already there. We just need to add the UI components to interact with
  the existing social functions.

  The main missing pieces are:
  1. Reply UI - buttons and forms to reply to notes
  2. Reaction buttons - like/emoji buttons on each note
  3. Note composition - form to write and publish new notes

  Would you like me to start implementing these UI components? We could begin with adding reply and reaction buttons to the
  existing NostrFeed component since the backend functions are already available.
