* Why is Offline Mode Important?

  Offline mode is essential for breaking the requirement that m2 operate in a
  network-connected environment. It means legitimizing a development environment
  in which there is no network connection, and providing a robust m2 service
  offering in such circumstances. Introduction of offline mode allows m2 to
