     - __shouldPauseOnSuspend__: Set to `yes` to make InAppBrowser WebView to pause/resume with the app to stop background audio (this may be required to avoid Google Play issues like described in [CB-11013](https://issues.apache.org/jira/browse/CB-11013)).
     - __useWideViewPort__: Sets whether the WebView should enable support for the "viewport" HTML meta tag or should use a wide viewport. When the value of the setting is `no`, the layout width is always set to the width of the WebView control in device-independent (CSS) pixels. When the value is `yes` and the page contains the viewport meta tag, the value of the width specified in the tag is used. If the page does not contain the tag or does not provide a width, then a wide viewport will be used. (defaults to `yes`).
     - __fullscreen__: Sets whether the InappBrowser WebView is displayed fullscreen or not. In fullscreen mode, the status bar is hidden. Default value is `yes`.
+    - __launchInNewTask__: When using target `_system`, sets to `yes` to launch system's browser in a new task. Default value is `no`.
 
     iOS supports these additional options:
