(author here) IMO KDE is the most authentic expression of Windows XP-era UI productivity that exists today. Their dedication to user-configurable settings is an absolute blessing.
This is one of the great joys of open source software. Provide a reasonable bug report and who knows, maybe even the main developer directly responds to it (and thanks you for your input).
For Microsoft Windows you can only hope that you have a big enough Twitter following to elecit a response from someone meant to contain the outrage.
Alternatively you might even be able to fix the bug yourself
Having recently switched to Fedora KDE, I agree. It is an excellent desktop experience and I think it's a great first stop for anyone interested in switching to Linux.
I had a good experience with Mint Cinnamon too, but the system seems overall better-integrated in Fedora KDE.
KDE is a great first desktop for anyone coming from Windows, but Mac users might be more comfortable with some of the more "Mac-like" desktop offerings available on Linux. But in that there ability you have one of Linux-based operating systems' great strengths. You can easily customize things to fit your preferred workflow. :)
Since Microsoft continues to treat Windows and its users like garbage, I'm fairly certain a Linux Desktop will be the lesser of two evils in my near future so I'm spending a lot more time working out how to live with it for my workflows. I discovered I really like Silverblue. Immutable OS with Flatpak focus and Toolbox cover a lot of what I want, even if the implementations are somewhat less than ideal.
Unfortuantely, Kinoite (the KDE spin of Silverblue) is hot garbage. Half of the things don't work including Flatpak icons (until a reboot) and running a GTK app in Toolbox causes it to inexplicably pause for several seconds at a time. I can't even report the latter issue (several of the former have 2 month+ open issues already) because the login for the bug tracker is busted. So I'm stuck with GNOME, a 'desktop' that desperately wishes it were running on a phone.
KDE is great though I really do have to configure it a bit to get it to be the way I like. I think I like cinnamon's out of the box experience the best, but I've also started using mate on a laptop of mine. Some things could use a little polish (like the way to move a task bar from one place to another is pretty much impossible to figure out without googling) but it's quite nice too, and it has the best file browser of them all IMO (cinnamon uses a nautilus 3 fork, but was forked after the point where they broke some things like type-to-search in folders behaviour)
To me, TDE ... a fork of KDE2, is even more so this.
A very active community, too, and so far, no real change. I don't want change, managing my windows, my open programs, is a decades old solved problem.
I don't want the new sexy, the flashy this and that. I don't want new styles, changing methods to interact. My Window Manager is not something I want to notice, or spent 10 seconds on.. for the next 20 years.
It needs to be in the background, while I do real work, or enjoy other apps. If I have to do things, configure it constantly, modify it due to new versions, it has failed in its task.
Anyone trying to vastly change, or improve this, is bananas. It needs no massive change, for 1000s of years.
