- Pros:
- system trays applet already works out of the box (still customizable to some extend at least more than gnome system trays)
- very good support for Wayland and VIDIA GPUs
- easy and quick to customize and you don’t have to deal with CSS if you don’t have much time to waste
- better integrated with KDE’s softwares (Kdenlive, KDE connect, Konsole, Kate, Elisa…) which is my opinion some of the best softwares for Linux even better than Windows’s in some cases
- friendly community (mostly)
- Cons:
- you have to use KDE with Krohnkite
It’s been a while since I last gave it a try, but I remember frequently ending up in strange states where a window wouldn’t want to tile properly. Windows would also frequently end up overlapping or extending beyond the screen, in ways they just wouldn’t when I was using Sway, Hyperland or Niri. IIRC mouse dragging and mouse resizing windows was extremely jank too.
Most of this is KWin’s fault as far as I know, it’s built for stacking window management and there’s only so much you can fix with scripting around it. It’s also the reason for the bad multi-monitor experience; the way it interacts with workspaces in particular is in my opinion not useful and never what I want.
Oh yes, that tiling issue is solved (if you had the same as me, but you probably had). I had huge tiling issues in the beginning of the transition phase from its codebase KDE 5 to 6 and on top of it on Wayland. It’s noteworthy that Kwin developers specifically addressed issues with Krohnkite, and even noted that in the update notes. I am using it quite some time now (a year or longer maybe) and it works basically correctly like any other standalone tiler.
Just my personal experience on a single monitor, as I am single. (yes I wrote that, just to make a joke, but I really use one monitor only)
