If you simply clicked on a category on the site you'd see what happens. I guess it's easier that I upload 4 pictures than that you click once on a link.
SYNC ON:
SYNC OFF:
As you can see, with sync on (img1, img2), the category listing menu disappears when I click on a category, e.g. swatch, even though it's set to display on every page in the same position, as i already simply said.
If sync is set to OFF, the cat listing stays there when you click on a category, but I also get a different style listing of the categories in the main content area (img 3).
