What’s new

- LISTS WITH ITEMS OF ANY LENGTH
Long items now wrap automatically into multiple lines. When editing, the
field accepts multiple lines too, and the list scrolls to top automatically
so you can see what you're writing.

- SMARTER SHARED-LIST IMPORT
When receiving a shared list, the app asks which group to import into
(instead of dumping into a default group). If a note with the same title
already exists, you choose: replace, merge items, or cancel.
