title: Can Chrome apps be set as default editor for a file type?
body: <p>I'm currently doing some research for a potential personal project which aims to be the default editor of it's own file format. Due to some desired requirements, it's nature and personal preference I'd be implementing as a chrome app and I was wondering whether you can register a Chrome app as the default application for a file type system wide.</p>
  
  <p>Registering it as available editor in Google Drive and other cloud storage solutions that allow it is nice and I can use an 'open file' dialog for getting user's local documents available for the app but a tighter, more traditional integration would be preferable.</p>
