Cart Creator Pro does what it does. It would be unrealistic to buy ANY software from ANY vendor on the premise that this feature, or that feature may be incorporated at some later stage. Planned features often get dropped because of integration problems, or changes of priority within development teams. Release dates get pushed further back by incorporating new ideas or encountering technical problems that can only be resolved by complete rewrites of large chunks of the code. That's the way it is with ALL software development,
whoever is selling it.
If I want to build quick, easy to maintain sites that 'fast track' customers through the checkout process, then I use Cart Creator, if I want to build more complex sites that need advanced features, then I use more involved software which takes considerably longer. Usually taking weeks instead of hours.
