KaOS is an independent, rolling release distro that only focuses on KDE and QT toolkit.
About KaOS, flip through the pages
Before finding and digging into openbox and Archlabs as a result, i have been using KDE mainly on Arch. There was a time when i though of only running mainly QT apps, and this distro fits what i wanted. Its an independent distro, but it uses pacman for package manager, so there is a similarity. in place of AUR is something they call KCP where some stuff are uploaded, including some common qt applications.
Other than that, it gives KDE quite a nice new look.
Has anyone tried this out?
