Enables/disables shortcut view by config.

Allows to enable/disable shortcut view by changing a single config.
Disable it by default because:
- Shortcut view can only work correctly with HAL support. It‘s up
  to every vendor to whether enable this feature or not for every
  project.
- Waiting for new UI design to avoid pocket dialing.
