Basically remove unused cookies that were last used from a day ago, a week ago, or a month ago. I do really want this feature cuz now it's eating up my storage. Besides, I don't want to remove all the cookies that I have. if I do, it will be troublesome when I need to log in to every website that I regularly used. Plus, it's good to keep our privacy by removing old cookies from sites that users rarely visit. Really hope that this feature become reality someday.
