How do I limit the number of products showing in the "Recently Viewed panel?

Hi,
I am trying to reduce the number of products showing in the recently viewed panel. The default appears to be 10. I can’t find a setting to adjust this - the options only show to enable / disable. The Specials panel, New Products panel and Pre Order panel are available to change.

Since there’s no option to set the number of products on the panel you need to update the Recently Viewed Items Panel template e.g.

      {forEach recentlyviewedproduct}

     {if (thisloop['iteration'] lte 4)}
....
     {endif}

      {endForEach}

Great - thanks Brian!
