Was going through a 'slideshow' of car models coming in 2020. Took a cropped portion of one photo (less bkgd) using Add notes in Edge (HTML). (Could, certainly, have put a wee note of explanation on it for when forwarding to a friend sometime* via Share ). The cropped image copied immediately/automatically. Then could drop (paste) that image into Bing Visual Search to learn all about that car & or related models, instantly. A neat, concrete, specific-example, use or 2* of Add notes done WITHOUT LEAVING the browser nor involving (needing) an outside app (such as Snip & Sketch). Quick, easy, handy & slick.
Whether this is in Edge C as part of Collections, as a solo act or both is irrelevant... as long as the function & ability is within the browser itself, that's what matters. Oh & not half of it, Share, buried in the ellipsis rather than side-by-side; unless referring to Collections.
