    Try to batch queries by multiples of row sizes
    
    This won't work for all MainWindow sizes, but will quite often be
    better than the status quo. As opposed to fifty, sixty is a multiple of
    everything from one to six, which means that it will ensure that the
    ViewContainers have full rows for a wide range of window sizes.
