How it goes in practice.
Make a home folder
Create a folder for the house with a shopping list, trip plans, warranty notes and the bin days.
Share it
Share the folder with your partner as an editor. Share a single trip note with a parent as a viewer, so they can follow the plan without changing it.
Use it in the shop
Tick items off the list on your phone. Your partner sees the ticks after their phone next syncs.
Plan the trip
Keep the bookings, the packing list and the day-by-day plan in one note, with a date like @due(2026-07-30) on anything that has a deadline.
