The great thing about menus and similar “universal” components is that the user only needs to learn one (or a very few) ways for how to discover things. One problem with modern UIs is that each app looks different and/or is laid out differently, and that there are a multitude of different-looking navigation elements and popup-menu buttons and/or sliding gestures. And of course that it’s often not clear what is just a label or graphic indication vs. a clickable button.
