    frequentView: Use BaseAppView.addItem() and loadGrid()
    
    FrequentView is another view that is slightly not unified with how
    BaseAppView expects subclasses to load app icons. Instead of using
    BaseAppView.addItem() and then calling BaseAppview.loadGrid(), it
    adds the app icons directly to the icon grid.
    
    Make FrequentView add icons using BaseAppview.addItem(), and load
    the icons using BaseAppView.loadGrid().
