Now that Lectora RCD is out, people will start actively designing courses for small screens. The three-line hamburger icon is a well known symbol for opening a menu on mobile websites and apps. But is it? I’ve read a number of opinions in the past year and many people think that the icon is confusing. I think today everyone knows that “floppy disk” is for “saving” but many people not only don’t associate the three-line icon with “see the menu”, they don’t even recognize it as a clickable object.
