I just added another version of Amazon Search 2.0 to my Sidebar.
I was not able to reduce the display to zero - I could only reduce it to 1 row.
I'll play with it and see what I think.
My initial reaction is that I like it better than the first Amazon Search 2.0 that I added to my Sidebar.
I was OK with seeing one item at a time and just clicking on the far right to progress thru the items.
I liked doing that a lot better than paying attention to the progression of page numbers.
Still I don't know who would ever bother with that - I would still rather go directly to the Amazon site and scroll down a page of choices.
