Hi, I had a quick question about the categories shown on the home page. In the demo for this theme, there are two categories per row, then 3 featured products and then 4 best sellers per row.

Is there a way to change the items per row, i.e. 3 items per row in all of the above? Do I need to change the views or the CSS? I searched in the Configuration settings and couldn't find anything.

Thanks in advance!

I found the option (though it only seems to be a square, i.e. same height and width) under Configuration->Media->Category Images.
