kwin-quarter-tiling VS material-decoration

There is also kwin-quarter-tiling, Grid-Tiling-Kwin, and just plain kwin-tiling.

Tiling: Quarter Tiling Kwin Script;

There's a kwin script for it, but I wish the tiling behaviour of https://github.com/Jazqa/kwin-quarter-tiling was more prevalent in all WMs and DEs. I'm not hard core enough to unplug my mouse, but I love having windows just sort themselves out automatically when I open, close, drag, and drop them, and this script has everything I could wish for.

Question, have you considered implementing locally integrated menus like in this decoration https://github.com/Zren/material-decoration ?

There is this project but I am not sure its the best way. It has an Arch and an rpm package, so you dont have to build it yourself.

You don't need empty space for that. GTK lets you drag from anywhere on the headerbar, buttons included. Similarly, the KDE material decorations which implements LIM also lets you drag from the integrated menubar. Buttons don't need to reduce the draggable area at all. Not that I want Plasma to have CSD of course, but having LIM available in official decorations would be nice.

You can get rid of menu bars. Most KDE apps use a hamburger menu by default now instead of a menu bar. Pressing CTRL+M lets you switch between hamburger menu and menu bar in KDE apps. KDE has no CSD tho and that's not something that's going to change, but you can move that hamburger menu to the title bar in window decoration settings. If you use the Material Decorations theme, you can even have your menu bar inside of the title bar. Or you can just use GNOME apps in KDE. That works too. But I mean, you've already said GNOME suits your workflow perfectly, so just keep using that. It doesn't seem like you've got any reason to switch to KDE.

My favorite implementation is locally integrated menus; this Material Decoration theme has it nicely implemented, but unfortunately it doesn't work on Wayland. I hope it'll manage to land in Breeze at some point.

There is a KWin decoration that supports this: https://github.com/Zren/material-decoration

Zren's Material decoration has an option to hide it, Breeze windows decoration doesn't.

might be easier to just remove the title from zren's material decoration then
