PS, from the official KDE Applications 15.12 release announcement last December:
Moving Forward
As part of the effort to modernise our offerings, we’ve dropped some applications from KDE Applications and are no longer releasing them as of KDE Applications 15.12
We’ve dropped 4 applications from the release - Amor, KTux, KSnapshot and SuperKaramba. As noted above, KSnapshot has been replaced by Spectacle, and Plasma essentially replaces SuperKaramba as a widget engine.
