ShinyCMS Features
Feature Flags
Quickly and easily enable or disable CMS features (e.g. 'new user registrations') in the admin area.
Rake task
Feature flags can be checked and controlled on the command line too, via a rake task:
rails shiny:features:list
rails shiny:feature:off[user_registrations]
Plugin status
This feature would be the very last one to be converted into a plugin - after User Accounts and Site Settings.
