Various suggestions
 

1: In an individual product if no reviews have been posted make 'date of last review' = 'No reviews posted'. At the moment if no reviews have been posted it displays the date that the product was uploaded.

2: When you choose to list all the products in a category (/reviews//showcat.php?cat=1):
* The ability to show a product thumbnail (like Photopost has the option to show a thumbnail for a photo category)
* The ability to switch some of the columns off. The 'date' column is the date that the product was uploaded - for me this column is totally unnecessary.
* A new column - the date of the last review for the product.
* The ability to list more than 24 products.

3: 'Product review thumbincluder' - the ability to show the product names (text block) or thumbnails (graphic block) of the last x reviews(actual reviews - not new products posted (someone did write a thumbincluder for the last x new products that have been loaded into ReviewPost).

4: A thumbincluder that allows you to specify the categories to select the thumbnails from.

5: 'Print product' button. This would format the page so that it's printer friendly just like vBulletin has the option to create and print a printer friendly page.
