Floral list is not just a checklist, but also helps you categorize and pack your travel items. List the item, its belonging category and bag, and change its status to "Ready", then there is no worry about "Oh my god, I forget to pack this or that".
All the default items are listed according to my personal experience. Add more or delete some, hit your trip.
