Additional Notes

Thanks for your PR. Looks like a solid Display Manager setup.
But I would prefer not to install a display manager by default. Many users prefer starting Hyprland from tty. Me, too, since my re-installation of Arch.
What about writing a dedicated installation script that can be launched from the Welcome App?

A quick note:
Simply installing the package is not enough.
I have implemented it in my system and with the installation.

If you're interested, here are the adjustments:
