  Long press now opens power menu (pure emulation of power button). Thanks to @cristianomatos
* Immersive
  Back on our first concept of having the tile dualized and change it:
  - Front: Toggles Global On/Off.
  - Back: Toggles modes (Full/Nav only/Status only).
  The tile now stores last immersive state, thanks @David96 for the idea.
  Fixed a critical bug with status bar hidden only, thanks to @David96.
* Rssi Tile
  Restore long press action to data usage on front rssi tile
  Fix icon overlay, restore blank overlay on disable and while wifi is on.
* Code indenting and cleanup.
* Restore a previous fix that relays on immersive.
