I sent in Apple/feedback on these exact challenges. The one thing I have forced myself to get used to is "resting thumb for a second on the screen to switch clock faces" instead of simply swiping. I liked swiping quickly between all sorts of "dashboards", I'd set the same watch face with different widgets and simply scroll left and right. That feature is now lost, an replaced with the vertical scroll feature that limits you to the BIG widget features, which many apps cram too much stuff into, and it is hard to read on a 41mm watch face.
I told Apple they need to break apart ultraOS from watchOS so that they can give the LARGE 2' ULTRA3 the changes they want while leaving the current watchOS features in place for the original form factor. We'll see.
The new dock is a pain, and no where as useful.
Control center need to come back.
- Drag-up for Control Center
- Scroll-Crown up for new Widget features.
Note: Modular watch face lets you "drag-right-to-left" to activate the app that is in the middle, but that is the same as tapping on the mile widget, so why waste the drag feature?
