Public lists — browse ready-made lists like Travel Checklist and Moving Day, then save your own private copy to change however you like. The original stays as it is.
Sections — split a long list under headings such as "Documents" or "Packing".
Copy as text — send a whole list to WhatsApp or your notes app from the list menu.
Also: a calmer first run with fewer example lists, and clearer list titles.
