Add full XYZ rotation please!

Full XYZ rotation would make creating  realistic models, stop-motion animations, games, showcases & so much easier, I'm honestly stunned that through all these years of KoGaMa existing, such a crucial feature hasn't been implemented! I know developers who have to use hacks to make their models rotate fully, it's kinda sad that they have to do that. I've been wanting this feature for forever! 

  The video here presents how KoGaMa could be with XYZ rotation, looks amazing, right?
