Shopping

This is a pretty simple, but sort of anti-pattern checklist. You either add new, or uncheck previously shopped items to add them to your shopping list.
You can add items via the top, or add them inside a recipe. If the latter, you'll get a link to the recipe.
Checked items are hidden by default, and when they're checked they're not saved. This means you have a list of previously checked items that you can go through for your weekly shop.
Edit or delete individual items using the edit button.
My workflow to go for a shop is:
- Show hidden items
- Scroll through the list and uncheck my shopping items
- Add any new ones
- (Optional) hide checked items
- Shop: check items off
Buttons

Very simple calendar view of your cooking history.
