I'm using klassy for decorations and krohnkite for tiling. I set klassy up to look like a cross between breeze and the windows 7 preset, but with outlines for tiling focus.
It reminds me of the Compiz days. There was a window decorator named Emerald, I think, that had themes similar to this. One thing that could change is the shadows when you're tiling. I would personally disable them. Preferably just while tiling.
ive thought about turning the shadows off but I can't really see them so it doesn't bug me personally. AFAIK you can't disable it only while tiling (bc the tiling script and the decorations can't interact with each other) but it is a highly requested thing on the krohnkite github.
default panel at the bottom with a couple small settings changed, default fedora 42 wallpaper. the terminals are just there to show the tiling and stuff without showing stuff from my apps bc the apps aren't the point.
edit: forgot the window decorations thing, I don't use them that much really but i put them there when I first started using plasma and now it feels wrong not to have them.
