After the age of puns being the peak of humour, the torch was passed to references. Also, the context of washing machines is so central to my concept of NSMB, that either subject can no longer be brought up without the other.
I like the trend of invisible UI. It keeps the display free of clutter and persistent UI elements (hello, OLED) and doesn’t hinder usability at all. I hide scroll bars whenever possible because middle clicking is far more convenient than click-dragging. Hidden elements always appear by using a related action–moving the mouse reveals the play bar, scrolling reveals the scroll bar. It’s completely intuitive. I even remove the forward, backward and reload buttons on my browser because gestures and shortcuts are just faster.
UIs are near-universally as clean and functional as ever… at least on macOS. Windows appears to be a clusterfuck. Linux is alright.
