No.
Been a fold user for going on 3 years now, and the outside display is pretty indespensible. Being able to use the phone as a normal phone, then being able to open the device and use it as a tablet, is the whole schtick. One doesn't really work without the other.
I hope they don't touch the UI honestly.
I respect your opinion, and I understand where it's coming from, but I find the switches UI to be basically perfect. No fuss, no fuckabouts, just gets me into the game.
I know this is a super divisive topic on the internet, so I know you're not alone in your opinion. I just don't really see what else would be wanted because for me, it does literally everything I'd want it to do.
Iron out a few hiccups, Bluetooth audio quick access menu, eShop speed, but buy and large, I love the streamlinedness of the Switches UI.
