KDE Plasma 6.6 Officially Released
KDE released Plasma 6.6 today, the latest version of the popular Linux desktop environment, also used in Steam Deck desktop mode. The biggest addition is the new Plasma Login Manager, a potential replacement for Simple Desktop Display Manager (SDDM) in distributions like Fedora Linux 44, CachyOS, and EndeavourOS. Note that it requires systemd, so it won't work on systemd-free distros. The Spectacle screenshot tool gains OCR capabilities, and a new USB portal lets sandboxed apps request access to USB devices. Users running Linux kernel 6.19 can now adjust the visual sharpness of all on-screen content. You can also turn your current Plasma setup into a global theme. KDE Plasma 6.6 adds XRandr emulation in KWin for better XWayland app compatibility, per-DRM-plane color pipeline support, and custom screen mode support in Wayland sessions. Screen mirroring is improved, and a new "Slow Keys" accessibility feature has been added.
Windows games with HDR running through Wine or Proton also get a color accuracy workaround. Wi-Fi passwords can now be stored in a root-owned location for better security, and a QR code in the Networks widget makes connecting easier. Battery handling on laptops is improved, ambient light sensor support enables automatic brightness adjustment, and colorblind user support has been enhanced. Windows can now be selectively excluded from screen recordings.
Other notable changes and improvements:

on one hand, moving my PC over to Cachy is gonna be a pain (nobody likes to do a migration of any sort) on the other, I'm already glad I'm taking those steps to get away from all this bullshit, sure is time consuming but I learned a great deal of things left and right while looking stuff up and almost none of it had a negative appeal to me

I'll stick with GNOME...
GNOME isn't perfect either, but it just feels better organized right out of the gate, and more modern too, like mid-late 2010's design language. Simple, clean, and functional, if not slightly goofy at times. But I can live with that vs a UI which clearly is trying too hard, to the users' detriment no less, in KDE.
Now, if after reading this reply, you found it ironic how verbose I had to be in explaining my initial, concise, snide remark, you can at least say you understand my beef with KDE.
And KDE Is hightly customizable, can be made very cluttered or very clean, it's a choice.
