Hamburger button? Is that what people are calling the three lines button? I think that&#x27;s one that will catch on. I didn&#x27;t get it at first, but I think now it&#x27;s here to stay. It also isn&#x27;t necessarily a sign of bad design. I think it&#x27;s mostly used as the &quot;main menu&quot; on a small mobile screen interface where you typically use the majority of the screen for information display. Not a bad design at all.
