I don't know if this is something everyone wants, but I would love if they updated the galaxy watches to fit more with the new aesthetics. These could include:
Changing the overscroll animation to the new stretch effect
Adding support for material you themes on new watchfaces, toggles etc
Improving animations and improving optimisation across the board
Support for Google assistant 🤞
I understand that some of these may be a google bottleneck not samsung, but if this is googles push to improve wearos, there needs to be yearly updates corresponding with mainline android updates that bring along new features.
