App doesn't prevent adding the same item twice

Thanks for the report. I agree, it should not be possible to add duplicates to a list. I'm afraid, I will not implement your suggested behaviour for now, because:

• Asking to increment the number of items won't work, because the amount-text-field allows strings like "500g" or "1 package". I.e. there is no universal way to increment the amount
• Filtering and autocompletion might conflict (I will have to wait and see how it actually turns out)

But I will design the autocompletion mechanism so that it does not suggest items that are already on the list.

And I will also make sure that an item cannot be added twice. I will only show a Toast (popup) notifying the user that the item is already on the list

I decided to allow duplicates, but show a little warning, if the item is already on the list. The main reason for that is the underlying data structure, which are simple text files. I assume that these files can be changed externally and there is no way to enforce that there are no duplicate lines in these files.
