@mint @RustyCrab It's a design gimmick to simplify interfaces. Mobile screens have limited input options (tap, long press, swipe) compared to desktop, and traditionally less hardware power; so less functionality is presented to the user. But if you put two tiny buttons and leave the rest of the screen blank, it feels like your app is empty (and they're harder to reliably tap). So they make fewer options look bigger. This design is reinforced by studies showing that mobile users tend to get frustrated the more they have to interact with apps. Just like web devs have those studies that show 60% of people stop using a site once they're required to login, and 90% stop when setting up an account requires an email. You could jam 50 options on a screen, but then a user has to scroll, squint, scroll, squint, maybe tap a sub-menu, scroll more, then finally hit a button that may be smaller than their fingers so they hit the one next to it. But users would hate it, the usage numbers would go down, and your dipshit manager who only knows how to read a Google Analytics Dashboard would freak out.
