Floris, the product XML you posted
here contains everything to make the setting appear.
All settings are stored in table setting, column value - each setting is identified by its Varname.
Title and Description are just Phrases, and those are in the Product XML as well.
So I don't really understand what you are talking about queries?
Also, please don't get me wrong on the redundant stuff.
I didn't want to argue, I just wanted to point this out, as others might not think of the possibility to just disable the product.
