What you can do:
1. Create a collection of shopping lists for all your needs.
2. Fill the lists with cards for each purchase: what and how much to buy.
3. Reorder lists in the collection and purchases in the lists as you like by dragging and dropping the cards.
4. Swipe Left to turn a purchase or list Off (do this when you've already bought something) or back On (when you need that purchase again).
5. Swipe Right to remove the purchase or list. Don't worry, you'll have 3 seconds to undo the action afterwards.
6. To edit a purchase card, simply tap on it and make corrections in a new panel.
7. Save the lists as text files in the "Documents/Lista de Compras" folder or share them with other ListaDeCompras users.
