I think it would be useful to display the enabled features in the debug info that is output to the console, E.g.:
DEBUG: -------------------------------
DEBUG: Ember : 1.3.0
DEBUG: Enabled Features : query-params, propertyBraceExpansion
DEBUG: Ember Data : 1.0.0-beta.6+canary.456107ba
DEBUG: Handlebars : 1.2.1
DEBUG: jQuery : 1.10.2
DEBUG: -------------------------------
Would anyone else find that useful?
