In keeping with the best-fit-only policy, the KaOS community deliberately keeps this distro's software stores limited. The current inventory is about 2,000 packages. The size will not grow beyond 2,200 packages. KaOS uses Pacman 4.1.2 as the package manager, with Octopi 0.4.0 as graphical front end. This is a good combination, as it's simple and effortless to add or remove software.
