    help-overly: Reduce maximum size of elements
    
    The shortcuts window was occupying more than 768px of height with the
    current set up of maximum items per column. Since our HIG recommends
    to support this size as minimum, we need to either redesign the shotcuts
    sections or decrease the items per column.
    
    This commit implements the later.
