Quickly create a simple Items list by just tapping on an Item icon under the search bar, but without having to also tap on the Done button

For those that don't add quantities or other info to Items, a quicker way to add items to a list.  

Touching an Item Icon would add the item straight onto the list and leave the search bar empty to start typing the next item with no need to press the Done button each time.

This should be an option in Settings to give people the choice of just quickly creating a simple list, or to add items and quantities as now using the Done button.
