tag (with color) an event you don't want to accidentally delete

like on email, where you are scrolling thru and deleting unwanted emails but you come across one that you want to look at later and you can check it, it turns yellow so you don’t accidentally delete it while doing a big batch delete…can we have something to make that clip be saved with a color so it is easier to find?
