SBSAR files as "Live filters" , like those in Affinity photo

Or maybe just a few simple ones  like height map to normal filter  , and normal to  curvatures.  Working as a adjustment layers, i.e  updating on the fly   rather  than   smart objects filters where you have to save first.

Once I tried "live filters" in Afinity Photo  I can't go back to Photoshop any more. They are so convenient  and so much more flexible.    

Pairing such "live filters" with ability to do your own in Substance Designer woud be super helpful.

I hate Sampler, it's so clunky and inconvenient , Photoshop could be a perfect replacement   with such addition.
