I use Tokyonight themes (https://github.com/folke/tokyonight.nvim) in most of my terminal applications. So, why should not use them in my #GNOME Desktop Environment as well https://github.com/Fausto-Korpsvart/Tokyonight-GTK-Theme ?

Using the install.sh CLI is quite straightforward, and you can choose the just installed look and feel by using GNOME tweaks tool (https://itsfoss.com/gnome-tweak-tool/). Some additional icons are also provided!

If using last #GNOME releases, this extension https://extensions.gnome.org/extension/4167/custom-hot-corners-extended/ is a wonderful addition to control your desktop hot borders.
