navigation buttons

Hi,
Now I have this problem to solve. It is an improvement!
So,
I show, like first page, all the categories of the products.
If you choose a category or if you choose a category and then a product you can't be able to come back. There isn't a button back.
I know that there is the browser button but if it is possible have one on the page i think it is better.

Yes, i agree with you, altought there are methods to sort this have something automaticaly sending you one step back in the navigation inside the catalog could be very good

I had already done this.
But it is not easy to understand for novice users.
But in Italy we say: Who is satisfied of a litle bit, enjoy !
