What you might be missing is some complex technical reason why the mouse control panel cannot be easily migrated. For example, a lot of drivers integrate their own tabs into the mouse control panel for features.
The slow migration from control panel to settings is actually, in my opinion, one of the better ways Microsoft has done software development. We aren't waiting 5 years for them to migrate 20 years of settings and we aren't stuck with a limited version 1.0 product without sufficient features.
I don't get people's enthusiasm for the settings app, I find control panel the faster way of achieving almost everything. Settings is slow and sometimes you circuitously end up where control panel world have sent you directly, e.g. when you want to change network adapter settings.
It’s a classic case of ease of use without experience vs speed with experience. Unfortunately, the former is the one that seems to win out with the masses.
Maybe there’s some sort of hybrid approach with keybindings for the power users and the blocky menu for more casual access.
The lack of keyboard shortcuts and tabbing means any setting I have to change repeatedly is a bunch of hard-to-automate clicks. (Namely, plugging into a new monitor and rotating it, since the Ctrl+Alt+UpArrow doesn't work any more.)
I agree. In addition, to me anyway, the settings app is kind of hideous. It follows some weird design principles and UI colors that don't even match the rest of the Win10 UI (even the new parts)! I would have expected to see something like explorer.exe - kind of a modern version of the older Win7 era UI principles.
