    WIP
    
    The general idea here is that, for every "window-mode-changed" signal
    emitted, we need to check if remote objects are to be displayed in the
    view or not.
    
    Therefore, there is _mode_specific function implemented. In the future,
    if we retain this approach, we can change photos_tracker_controller_mode_specific
    to be a virtual function. This way we can have a common place if for any view
    something is to handled specifically.
    
    This is just a sketch.
