List App

I would like to have the App add an existing item to a list of things to buy by selecting it from a partially typed item name.
I would like to have all lists show there are items to buy on each them by having a green check appear adjacent to the list name at the list home page.
I would like to have the App "gray out" the items on the active list of things to buy and keep them there to remove all at one time.
This App is an 8 of 10 for me.
