This is a good idea.I don't have to start over for my next time shopping. Thanks for the feedback. I will try to add this feature when time permits.
That is a good idea, however not what I actually meant. I meant that when you add a new item to the lists (by entering in the text box) it could be selected automatically - because if you add it, you probably wanted to tick it but found it was not in the list.
I added this feature yesterda i.e after adding new custom item its checked and in the shopping list. I talked with another user (off HN) about this yesterday, maybe it was you.
