PreferencesManager.getPreferenceStorage is deprecated #40
Description
The Brackets method PreferencesManager.getPreferenceStorage() has been deprecated in Sprint 36 (released February 2014) and is about to be removed in the near future, probably in Release 1.1. Your extension makes use of this method and thus, it'll probably not work any longer after that code is removed, or it will at least behave wonky.
Use the new Preferences System instead to be future-proof.
