But, now that the edit notification have been add, do one still need to add the "edit" world before adding their sentence since the notification doesn't indicate any specify edition but the whole post?.
That's not necessary, it's up to you to use the word "edit" when editing a post.
And nothing especial since it's only implemented to mobile browsers, same thing for desktop browsers as the hover thing. Btw that's not an
editing notification.
