Thank you for your comment @pavlvus !
Those are two great articles, thank you for sharing. There are countless Cas9 protein fusions that have been published in the past two years but I agree that the chromatin-remodeling or nucleosome modifiers are of particular significance since epigenetics studies still lack this kind of tools.
If you are interested in other applications, one that i am particularly excited about is the RNA editing by Cas13 mutants:
