there is an option to choose Hide Categories, which is excellent.
but my problem is that i have a lot of categories which needs greate separation - each Gellery menu (i have about 15) needs to show only its relevant categories.
every time i add a new category - i need to go over the rest of the menus and choose to hide it, and i have tens of categories (60 so far...
is it possible to add a small '!' so that if i insert ![cat_id] in the Hide/Show categories field, it will only take this category and not the rest?
