I'd like to provide such features. I'd also like to go so far as to
categorize food items and attach prices. However, the focus has to be
on the health related features. Until we have a perfected total health
tracking application, shopping won't receive much attention.
Incidentally you are the first user to indicate that shopping is
useful! I implemented it as a simple "whiz-bang" feature that I
wanted. I'm glad others are finding it useful!
