So, I have my main product list set to List view through the Presentation Settings-perfect.

However, my list of Products in the categories view is using grid view as the default display. Short of modifying the plug-in code, where can I control that display so that every category list is the list class (list view) and not the grid class (grid view)?
Of course, client panic 3 hours before a long weekend (in the US)!
