Today, I have tried Apper and in my utter surprise, I could install, remove arch Linux packages in there. I know you guys have your hands full but if discover wants to be the universal package manager for KDE it much have this feature. Just add it to the lowest list.
Discover & PackageKit have supported ArchLinux for years (I'm an ArchLinux user and develop Discover on it).

Am I missing something? I don't see any arch linux package list.
Sorry missed the optional dependency. Problem fixed.
:) cheers Further feedback welcome!
