I have seen many sites that have a customer feeback (?) sidebox. Can't recall the "proper" name for it, where a customer can basically put in their feeback regarding the transaction etc.

When I first downloaded ZenCart I could have sworn there was one originally there (maybe it was something else) but I since removed a lot of the sideboxes etc that I didn't need.

I have gone into my admin to "turn it on" so to speak but can't find it now.

Can anyone help at all?
