Add a locked shopping/task list feature
I would like to create a locked shopping list so that way I can always visit it over and over again when I want to make that certain meal at home.
I want to make tacos
I would select the tacos shopping list
Then I would check off items I get while at the grocery store.
Then next month if I decide to make the same dish again I could select the saved shopping list and use it over and over through out the year all while being able to modify my locked list if I need to.
Same goes for events, IE I like to throw birthday parties for my kids so I would select my locked birthday party list and it auto adds Cake, Candles, balloons, and food etc.
