QUP Karaoke Engine v2.18.1 is out.
Plugin updates work. The Plugin Browser's Update button now installs the new version (it used to remove the old one instead), and the Windows installer clears out plugins an older QUP left behind, which showed as built in and could not be updated.
Smooth music video backgrounds with the Backgrounds page open, and KaraFun is pre-fader on the spectrum, starts its player with QUP and is lighter on the CPU (KaraFun 0.1.3, in the Plugin Browser).
