Superfish functionality

Superfish functionality

It seems to me that in a Superfish dropdown menu on touch screen it is not possible to dismiss a submenu with a second tap on its parent item - it is only possible by tapping anywhere off the menu or by tapping a different item to open another submenu.

I am good with css but am not a jQuery coder. Would it be relatively easy to adjust the plugin so that a 2nd tap on the parent will close a submenu?
