yes, the crossed off section gets VERY MESSY with so many duplicates... having one of each thing would make it much easier to tap and add rather than type in again.

Yes please!

I go to two different supermarkets and they order things differently, so using the colours to organise stuff in different "areas" only works with one shop, because the products (list items) keep their colour for all lists. Naming the colours, and having more of them, AND being able to have different lists each with their own colours/categories would make this a far better app. At the moment it works well, albeit simply, for one shop only.
