• Reply to message (Using ReplyID on Message)
• "Tapback" emoji responses (Easy access to the subset that works on device screens, can allow any emoji)
• Github flavored markdown rendering for message text body
• Ability to @User with deep-link to node detail and notification options
  • Users can @ another node by typing the @ symbol Long name, short name, or user.ID
  • The actual text payload representation should package this as the User.Id: "@!ffccee11" for the wire
• PKI secured indicators for direct message threads to a node
