But for something like a phone or messaging app, I want to see the return of fun, creative, and unique. We had such a great era of design around 2006-2013 and then it all rapidly went incredibly dull since then.
I want to see creative menus back, I want to see whacky UIs like windows media player skins back. Ultimately for basic stuff of low importance like your phone, the most absolutely optimal UI doesn’t matter, much like I don’t care for the most absolutely optimal furniture. Its visual appeal matters.
