I searched for this topic in the hotline and see nothing new since 6 years ago.

There are work arounds, depending on your aims:
• cook or use up ingredient on hand
• know your collections better
• edit or eliminate recipes with ingredients you are no longer favoring
• et cetera
Not an answer, but a second to the motion. It would be really helpful to have a way to limit searches to favorites or saved collections.
