 - **High capacity** - Hyprwall can handle a large number of wallpapers (over 1000 at one time!) without any issues.
 - **Multiple monitors** - Hyprwall supports setting wallpapers on **Multiple** monitors at once.
 - **True async** - Hyprwall is built to be asynchronous, it uses tokio to run commands in this manner massively improving performance.
+- **Cli args** - Hyprwall supports command line arguments, to view these type **`hyprwall --help`**, **--restore** is one of them, if you wish you can restore your last used wallpaper in the gui with this argument.
 - **Supports swaybg, swww, wallutils, feh, and hyprpaper** - Hyprwall supports a variety of wallpaper backends, so you can use it with your preferred wallpaper tool.
