    appDisplay: Add intermediate stack widget to hold folder popups
    
    AlphabeticalView will be updated to allow app folders in addition
    to app launchers. Folders will pop up in the existing view, so add
    an additional stack widget into the hierarchy which popups will use
    as parent.
