Thank you for the answer. I'm sure you can tell by my previous post that I for one would prefer to have the modules split for the greater flexibility. I have used Catalook on previous client sites and the major drawback of it is the level of complexity; that being said it has just about every feature you could want in a cart module.
So far I really like your cart, even better than Catalook, and am glad to see the active development of it. However, in order for it to be a cart module that I can use on a number of client websites it needs some greater flexibility. I hope my comments will encourage steps in this direction.
One last thought: what about a "lite" version that would keep things very simple and a "full" version that would allow a more advanced flexibility? (no response necessary... just an idea)
