Say you could really reuse an old list, make some minor changes to it… But still keep the old one for reference?!

You can use any list as a template for a new one! Simply go to the 3 lines menu and press “New list”. From the sub-menu, select “Create from existing lists”. Check the preferred list and press “New list”. Choose a name for your new list, and you’re good to go. …Shopping, that is šŸ˜‰
This comes in handy when your style is to keep master lists that you only slightly change to suit your weekly needs.
