I would like to either reuse the default activity types or create new ones with some of the default ones (the ones available are very limited).
So please either: add more icons (also those used for default acitivties, or the ones that are not used at least)
or let edit the names of the default activities.

It would be also pretty cool to be able to edit misspelled positions on the lists.

(1) Let user can edit or delete the category, some of them are no use for me. And I want to edit the category title in Chinese.
(2) I want to arrange the list in my style.
(3) Please add the back up function, so that I can save the list.

I think you should have it so when you open the app you can see all your trips in chronological order, where you can pick an icon (beach, city, camping, etc) and there be a countdown till departure. Eg, Sydney (5 days).

I would like arrival date & departure date please

At the moment categories and their content are not organised alphabeticaly or manually, making it confusing and inefficient for packing and planning. This feature would make it a true 5star app.

Umbrella, bug repellent, sunscreen, rainwear, travel pillow, walking shoes, pen, and small backpack or tote should be added to the packing list. Additionally, beach towel, hat, sunscreen, swimsuit cover up (for women), UV protection clothing, water shoes, float(s), and pool toys should go under swimming and beach. Beach could also use beach blanket or mat and beach umbrella. International could use foreign language book and pen. I see people asking for a pen to fill out the entry and exit forms on a plane all the time.

You can turn off or hide categories but it would be nicer to delete ones you'll never use.

If I mistype an entry, or want to change it afterward for some other reason, I have to delete it and recreate it. This gets old pretty quickly when typing on a small phone.

It would be great if you could change the order of items listed. Both the standard and custom lists.

The ability to reorganize/sort the list (done, not done, alphabeticly, customer order, by type, etc).

Planning a journey with multiple destinations and different weather conditions.

Allow items to be manually rearranged. (If I add "tanks," I want them next to shirts).

Many of us pack by category/ suitcase. Having clothing in its own category woulf allow added items to properly display with the rest of clothes.

I think having clothing as the first category to show also seems logical.

Allow me to view my packing lists on multiple devices - e.g., my phone and my tablet

Show what others packed for this location, weather and date

When I add my own items to a list then store those in the cloud and suggest them on top of the static list.
