clean gui for installing shit from the repos or AUR
I believe this is because applications can be submitted by anyone in the AUR (Arch User Repository), and having a simple GUI where you can one click install is a decently big risk. Not a huge risk, but somewhat big. Both base Arch and EndeavourOS, the latter of which I personally use, do not ship with any GUI for installing AUR programs. I find that using something like yay or paru works perfectly fine for me
And of note, CachyOS now ships with the Shelly GUI package manager, an actively developed one that is relatively new and combines Flatpak, AUR, and Arch repos in one location. Pretty neat I think!
