Yeah, it's kind of their main selling point for the studio version Without that there would be almost no benefit to pay a 1000 $.
The reason why I have been following Fusion is because it's free even for commercial use (compared to the free non-commercial Nuke) and it is now in the hands of Blackmagic Design who have made amazing things in the past, so I am curious to see how it will evolve.
Indeed it is ! I like to compare Natron with Fusion to see where it could be improved. Since Natron's main inspiration is Nuke, I find it useful to compare it with something similar but different (if that makes sense).
