```ruby
require 'rails'

module Bettertabs
  class Engine < Rails::Engine
    initializer 'bettertabs.action_controller' do |app|
      ActiveSupport.on_load :action_controller do
        helper BettertabsHelper
      end
    end
  end
end```

Add comment to initializer that includes BettertabsHelper
user
```ruby
require 'rails'

module Bettertabs
  class Engine < Rails::Engine
    # Ensure BettertabsHelper is globally available.
    # Otherwise, if config.action_controller.include_all_helpers = false, the Bettertabs helper would not be included.
