The thing with the Control panel (speaking as a former Windows user up until a year ago) was its consistency. Since the Aero era things have remained in more-or-less the same place. Sure, some things got added, some renamed and some deleted, but the basics I needed (mouse sensitivity, battery settings on the laptop, the Add/remove software page, search indexing, printers) has all stayed in more or less the same place.
Then 10 happened. And sure, Settings was great for a lot of stuff. But when Settings didn’t have the option (or I lost my nerves trying to find it), Control Panel was the way to go. I’d find what I needed pretty much instantly, since was always one of the same 20-odd things I need.
Even then, everything just seemed faster in Control panel. Was it more responsive? Were there less animations? Were more things crammed into one screen so less clicking and scrolling was involved? Is it just my imagination?
Honestly, I don’t know.
By the time I got used to the new Settings app, one of the big Windows 10 makeovers happened and jumbled up about 10% of Settings. Objectively not much, but just enough to irritate.
And now with 11, they not only made Settings unrecognizable, they also cranked the spyware up to, well, 11. And there’s no Control Panel to default on when in doubt (or fuming with rage).
All in all, while Control Panel wan’t what kept me on Windows, 11 losing it did ease the transition, since it meant having to learn a new way of doing things either way. Might as well make it a way that hopefully won’t change once a random design exec decides “this is ugly and it has to go”.
Honestly, KDE Plasma’s Settings are where it’s at. It’s right between the functional and informstional density of Control panel and the simplicity, visual appeal and saner structure of Settings. Shame it uses Qt, which from what I hear, is god-awful as far as UI toolchains go.
Dark mode can be recreated using extensions, although the colors most likely won’t be as legible as “native support”.
I don’t see why a similar extrnsion couldn’t change the timezones of clocks.
Additionally, I don’t see why the server should bother with either (pragmatically) - Dark mode is just a CSS switch and timezones could be flagged to be “localized” by the browser. No need for extra bandwidth or computing power on the server end, and the overhead would be very low (a few more lines of CSS sent).
Of course, I know why they bother - Ad networks do a lot more than “just” show ads, and most websites also like to gobble any data they can.
