Reset-able list or list items would be great. I don’t have to-do items I do every day, but I do have items I need to get each time I go to the store. So mixing permaitems and one-shot items in ine list would be awesome.
Maybe these items could be indicated in a similar manner to using a colon for headings and a leading space for smaller type. And then only if that special character appears in the list, a refresh button—like the reload webpage button in Safari—would appear at the right side of the list title bar. Push the button and cleared permaitems reset. Oh! And the special character could be a leading at symbol @ because it is visually similar to the reload button. Maybe when entered the items appear bold or italic it something.
E.g.:
@eggs
@milk
Chicken wings
Hot sauce
Appears as
Eggs
Milk
Chicken wings
Hot sauce
Clear each as normal, then refresh when done. Cleared items disappear and permaitems repopulate the list.
