I'll give you some quick ones:
-Wipers: One less step to choose the speed.
-A/C controls: Having the button closer to the driver makes selecting the temp and other controls within its window easier. The fan control slider is also easier for me to quickly select a speed. I live in S.FL so heated seats are the last thing I need on the UI, however, it's easy to get to. Defogger, something I rarely use, is also easy to get to and no need to be its own button. Plus, the defogger / defroster takes a while to take effect so I fail to see how an extra second to select it would matter. Also, in the really cold weather people face up north, as soon as they get in, wouldn't they turn on the heated seat function immediately, even before driving off? Same with the defroster if it's often needed? The app also has a defrost button.
-Dashcam app button: Being something that I use often and, on the fly while driving, it's nice to be able to place it in an easier to reach location.
-Blind spot cam: I think most would agree this is a plus although its positioning could be better.
-Dashcam status icon/button: Bigger and easier to select to save footage. The previous icon on the UI was small and needed a little more concentration to select. And I never liked the idea of honking the horn to save footage.
-Music is easier to navigate and the drop-down menu is an improvement.
-PRND status is now bold and easier to see.
-Speedo readout is little more in the line of sight with this update.
