## `file_handlers`

See https://developer.chrome.com/apps/manifest/file_handlers. 
This is useful for Chrome OS users. You can experiment opening files with certain Android apps by setting their file handlers. Add to `manifest.json` in your app: 
```
 "file_handlers": {
      "any": {
         "title": "Open with SOME_APP",
         "types": [ "*/*" ]
      }
