 Personally, I integrated the .desktop icon in my top bar.  
 It is the first icon from the left.

 When `arch-update` is checking for updates, the icon changes accordingly (the `check` function is automatically triggered at boot and then once every hour if you enabled the [systemd timer](#the-systemd-timer) and can be manually triggered by running the `arch-update -c` command):

 If there are available updates, the icon will show a bell sign and a desktop notification indicating the number of available updates will be sent (requires [libnotify/notify-send](https://archlinux.org/packages/extra/x86_64/libnotify/ "libnotify package")):

 When the icon is clicked, it launches the relevant series of functions to perform a complete and proper update starting by refreshing the list of packages available for updates, print it inside a terminal window and asks for the user's confirmation to proceed with the installation (it can also be launched by running the `arch-update` command, requires [yay](https://aur.archlinux.org/packages/yay "yay") or [paru](https://aur.archlinux.org/packages/paru "paru") for AUR packages update support and [flatpak](https://archlinux.org/packages/extra/x86_64/flatpak/) for Flatpak packages update support):

-You can optionally configure `arch-update` to not show the version changes during the package listing (see [Tips and tricks - Do not show package version changes](#do-not-show-package-version-changes):

 Once you gave the confirmation to proceed, `arch-update` offers to print latest Arch Linux news.  
 Arch news that have been published within the last 15 days are tagged as `[NEW]`.  
 Select which news to read by typing its associated number.  
 After your read a news, `arch-update` will once again offers to print latest Arch Linux news, so you can read multiple news at once.  
 Simply press "enter" without typing any number to proceed with update:

 While `arch-update` is performing updates, the icon changes accordingly:

 When the update is over, the icon changes accordingly:
 
-![top_bar_up_to_date](https://github.com/Antiz96/arch-update/assets/53110319/794696a0-3452-4afd-8d64-a41d64225082)

 `arch-update` will then search for orphan packages/unused Flatpak packages and offers to remove them (if there are):

 `arch-update` will also search for old and/or uninstalled cached packages and offers to remove them (if there are):  
 *The default behavior is to keep the last 3 cached versions of installed packages and remove every cached versions of uninstalled packages*

 Additionally `arch-update` will search for pacnew/pacsave files and offers to process them via `pacdiff` (if there are):

 Finally, `arch-update` will check if there's a pending kernel update requiring a reboot to be applied and offers you to do so (if there is):
