Inventory control: Even though it doesn't affect me as a seller, as a buyer I'd be annoyed if I bought something online, paid my money and it was no longer available.
Sub categories: Scrolling way down the pages is good for nobody, it looks messy and unprofessional.
Price variants on options: Many sellers have price related variants. Many of those options cost extra money. Having those variants in a drop down list gives the customer a wider range of buying options and gives them a choice of products all within one listing.
Stock numbers: Again this doesn't affect me personally, but can see massive benefits for sellers selling a lot of very similar products. Easier for offline stocktaking too.
Better shipping options: At the moment the shipping options are far too restrictive and totally inadequate for serious use. A weight based shipping option with user definable weight tables for user definable destinations would benefit everyone that ships physical goods. No business can afford to lose out on shipping charges, or end up overcharging their customers.
Digital downloads: Not a market I am in myself, but I've seen many requests for this feature in the forums. Could be an extra revenue stream for other users as well though. For the cost of a domain name, why not have a second 'digital' shop?
Zoom on thumbnails: I like the simple layout of cart creator, but a mouse over zoom on the thumbnail images would present the products better, without diminishing the number of items on the screen. Those little javascript auto zooms really look elegant and would be a huge benefit to customers.
Most of the above features are already on the 'road map' for the pro version of the cart creator and I'm sure that other folks will add other ideas to this wish list also.
Like many others, I must have tried out over twenty different cart offerings before I discovered cart creator. Whilst it still has some shortfalls in some areas, I strongly believe that once features like the ones above are incorporated into the pro version, we'll have a class leading product to create shops to do what they are intended to do; namely to present our products in the best way possible, give the buyer a pleasant environment in which to browse and most importantly of all, an easy and secure way in which to rapidly pay for those goods.

Cart creator is a simpler solution to having a shop online. It is not overburdened with features that few people will seldom use and it certainly doesn't have the endless problems that using larger database solutions create. When you add to this wish list, keep in mind the ethos of 'a simple workable solution, that benefits the majority'.
