Re: Several Layout Questions
Hi
Here you go :
# 1 To turn on/off sideboxes and to rearrange the order they show on your cart, and also to move them left/right you use the Tools/Layout Boxes Controller. This is in the admin area of your shopping cart. This answers both #1 & 4 for you.
# 2 To turn on all of your sub categories is also in your Admin area - you need to go to Configuration / Layout Settings - there you will see the setting to show subcategories or not.
Sorry, don't know about your reviews question but hopefully these things will help to point you in the right direction.
