NIK You must be talking about Yum :-) because shopping list, and other database-type features have been on the to-do list for Yum for some time. Hopefully before the end of this year, but hey, it's free software so in my own time.
By the way, does anybody know how to get the administrators of this web site to change the product name from "Yum!" to "Yum", as I've tried to get them to do several times?
