 ## Wallpaper & Colortheme
 
 - [WallReel](https://github.com/Uyanide/WallReel): an Image Carousel implemented with QtQuick to browse and set wallpapers from.
 - [change-colortheme](./config/scripts/.local/scripts/change-colortheme): script that extract colors from the current wallpaper and generate a catppuccin color scheme accordingly.

+## Hyprland & friends

+## Eww

+- `main`, main dashboard, modified from [syndrizzle/hotfiles](https://github.com/syndrizzle/hotfiles/tree/bspwm) but without notification center.

+## Swww
+
+The wallpaper will be automatically blurred when there is a window in focus, which is implemented in the [wallpaper-daemon](https://github.com/Uyanide/dotfiles/blob/main/.scripts/wallpaper-daemon) script.
+
+This feature is only enabled in Niri. Swww also manages wallpapers of the Hyprland setup, yet only in the regular way.
+
+## Wallpaper & Colortheme
+
+The most suitable primary color (or so-called flavor) will be chosen from the [Catppuccin Mocha](https://catppuccin.com/palette/) palette and applied to various apps automatically after changing wallpaper. And also:
+    
+- [wallpaper-chooser](https://github.com/Uyanide/Wallpaper_Chooser) to select wallpaper, which implements an Image Carousel with Qt Widgets.
