Hello guys.
I am new to this CS-Cart thing and I have a first question.
On the home page, products appear in 4 columns so i want to be change from 4 to 6 or 7Colums.

What is that called and from where can I change the number of columns and rows? I made a picture so you can see what I am talking about.
