This is not possible. Corners were done with ags. Actually, now the whole bar is ags, I don't use waybar anymore. But the design is the same

Btop also supports catppuccin theme)

Not for all widgets)

That's easy! Mr Kitty - After Dark

However, Yandex works under Russian jurisdictions. Brave search is ok

He doesn’t want Xitter to get banned in Russia

Well, It has been blocked for 2 years now. How Do You Like This, Elon Musk?)

It's not a default one, name is HiQDock. Though, it's not very usable. As there's no transparency supported, it takes screenshot of a background, so it might cause graphical glitches. The default dock (see the screen with Cave Story) is much better, works perfect

Waiting for Plasma6, will give it a try

The code have not been refactored yet! README is not correct now. I'll let you know, when everything is ready)

In order to figure out, what's Nix, how to use flakes and home manager, I'd recommend watching LibrePhoenix. It's absolutely fantastic guides. His repo with Nix config is also great, it's the one, which I'm gonna take as a reference

Please, give me some time, the repo is messy as hell now. If I were you, I would not do that now. I'm going to refactor the code, make it more modular in order to allow several WMs and themes. I'm also gonna introduce instructions for installing all of this)
