I have two recommendations for version 4.1 before it becomes finalized. I know this comes a bit late in the game, but I thought I would put them forward anyway.

The first one is simply to record the transaction ID with the advanced info by default for credit card processors that support this. Having this ID handy makes issuing refunds faster by eliminating the step of looking the ID up by card number. This is very simple to do and I have already implemented it on our setup.

The second one is a bit more complex but I believe it would be worth while. That is to divorce image.php and product_image.php from the rest of the cart. Instead have these load up only the minimum variables and include files needed to show an image. Loading up config.php each time also causes Smarty to load which is completely pointless when simply outputing an image. Minimizing resources called upon by these two scripts would save significantly on server strain as they are called seperately for each and every time a product image or thumbnail needs to be shown on any page, meaning that each and everytime they must reload and include all of those other redundant PHP files.
