Parse "(?)" prefixed to a item as "No category" and ensure that this isn't overwritten by automatic category matching

Port client functionality that automatically finds a matching category from completions

This helps users who want to navigate mostly by keyboard instead of mouse

Recently deleted sould be removed once they are older than a certain threshold. Show top completions instead

This happens e.g. when pushing the home button

• TopBar should be more flexible, to make it reusable (e.g. for ChooseList)
• connection state from TopBar
• "list" part of ShoppingListComponent
• form from CreateItemComponent

For example, I'm not gonna add the item "Müllbeutel 15l" anymore because I discovered that "Müllbeutel 25l" works better for my trash can. I find seeing "Müllbeutel 15l" in the history confusing and would like to remove it.

Button to combine to items with same name, category and compatible units

Add button to automatically convert units to metric

Pressing enter when adding an item adds the item, while pressing enter when editing an item adds a new line. I expect to add a new line by pressing shift+enter and exit editing by pressing enter.

On the main page, there should be a button and a lineedit for the title to create a new list.

Add a way to share/export the link to the list. Normally, this would be accessible from the browser interface, but not in the installed progressive web app

There should be an option to transfer a sorting from a list A to a list B. In my opinion, this should also include adding any categories from list A to list B, while not deleting any categories from list B.

See

• https://developers.google.com/web/fundamentals/web-app-manifest/
• https://developers.google.com/web/fundamentals/app-install-banners/

When viewing the categories in a small window, the formatting is off, see picture:

There should be an option to transfer the category assignments from a list A to a list B. In my opinion, this should also include adding any categories from list A to list B. When the category assignments of list B are changed after the transfer, the category assignments of list A should not be changed. Existing category assignments for list B should not be changed during the transfer.

Similar to etherpad welcome page, to allow creation of new lists

In Firefox on Android, the newlines in the hint text of the extended input field are not shown. Maybe bug in Firefox?

In firefox mobile, the page is wider than the screen, with a weird empty space on the right.

With some mobile keyboards, a space can be inadvertently added when using autocompletion. For example "listname" and "listname " are different lists, but the user might not have noticed.

Paste in multiple items at once

Use case: I want to know whether milk is not on the list because someone else already bought it, or because it was not added yet
