I'll try something different next install, I swear.

I’m still stuck on i3 and sway. I hear there’s a version of KDE that is tiling…? But I haven’t found anything definitive on that.
Kwin supports tiling, although nothing stops you from replacing it with i3.

I’ve heard this which made me assume it was like an option I can just enable, but every search has only come up with some baroque scripting or configuration guides, which seems like a lot more work than just using an actual tiling window manager.

E: Oh I get it now, you just install Krohnkite. This is a bit of an improvement, I will admit.

Yes, scripts like that exist (or replacing kwin). I don’t do it anymore, so I didn’t have recommendations, but may check this one mentioned.
