A bit late posting this, but version 1.5.0 is now in the App Store.
v1.5.0 brings one new game, a way of re-using Quiz questions, and some general background improvements.
You can now host your own Karaoke night, and let your guests belt out some bangers. The software supports MP4 and CDG files, which you need to provide yourself.
There is now a feature in Quiz Management that lets you re-use Rounds and Questions that you have already created. From the new section at the bottom of the screen drag an existing round into quiz, or drag a question into a round.
