bismuth VS materia-kde

What level are you interested in scripting? In KDE Plasma you can interact with the desktop UI via JS: https://develop.kde.org/docs/plasma/scripting/

And then for something more sophisticated there are extensions like https://github.com/Bismuth-Forge/bismuth.

It does all feel a little disorganized/wild-west-y compared to say, a .vimrc with a list of plugins and bindings, which is something that makes a system like Nix (or a fully containerized DE of some kind) appealing

It had, but they are all dead until ported to the new kde 6.

This is what I used. I found no good replacement for it and that is what made me switch to hyprland.

one thing i would totally recommend for kde is bismuth https://github.com/Bismuth-Forge/bismuth/

it's tiling for kde and it works REALLY well.

Take a look at a tiling window solution. I'm currently using bismuthwith gives similar arrangement to what you're looking for and helps massively with productivity when working on an ultrawide

As a good halfway house you could do worse than KDE with Bismuth (https://github.com/Bismuth-Forge/bismuth), which is an add-in that will give you great tiling capability, fully controllable via the keyboard. Couple this with KDE native virtual desktops and you have a pretty decent tiling window manager.

Plasma 5.27 added in some native tiling support. There are also some kwin scripts available to add tiling to it.

Not-good stuff: This tiling is very incomplete. It doesn't allow you to snap everything to your tiles at once, it doesn't support different tiles per virtual screen/workspace and, perhaps more importantly, with that addition and Plasma 6 on the way, compatibility with Bismuth and similar addons is getting lost.

Since you are already using KDE, you can very easily try how much you like tiling: just install bismuth: https://github.com/Bismuth-Forge/bismuth It's a plasma add-on that enables tiling in KDE. If you don't like tiling, just disable the plugin again and uninstall bismuth.

No, it doesn't have that. Here is the list of layouts.

No I was talking about Bismuth which was amazing and actively maintained but due to kwin updates it's not working and is apparently not going to be updated

AFAIK the default theme, at least for GNOME, is now Materia-dark. Would be an easy process to make it the new default theme for Budgie and MATE with the upcoming ISO refresh. The only things about it that kind of blow are that we're going to lose the "true black" which Plata-noir provided, as well as how it could be implemented for KDE Plasma (Materia KDE doesn't seem like an elegant solution)

install Materia kde and set it as global theme. Double check to see if plasma theme is selected to materia. You might as well log out and log back in.

Broken windows titlebars and widgets after resume from suspend/hibernate, but turns out it's a known issue (thanks to u/Matty_R for mentioning it)). No issue with titlebars if I stick with stock Breeze windows decorations. I'm using Monochrome KDE and it also occurs with Materia KDE. Widgets can be fixed too with that method but it's a hacky workaround.

I've installed the Materia KDE theme on a fresh installation of Kubuntu 20.04.2 along with kvantum and I realized that when I lock the screen, it is not working correctly, only shows a wallpaper but not the login controls so I'm not able to login again.
