Parametric Filters feedback and ideas

This is one of the most exciting features I have seen. I use Filter Forge sometimes, but it is clunky to have an image open in another program. I think parametric filters will be able to do many of the things Filter Forge does while having the power of being a native smart filter. I'm learning how to use Substance Designer just to create my own Parametric Filters. The filters fill gaps I have always felt were missing from Photoshop.

I currently mostly use the filters with photo compositing, doing things like lightning effects and "degrading" things like 3D renders that look too perfect. I think it also has amazing potential for uses like text effects, 3D effects, metallic effects, etc.

There is only one major thing I would love to see changed. I would love for it to apply to the layer I'm on, and not make a duplicate, especially if it is already a smart object. (currently, even if the layer is already a smart object, when first applying a new Parametric filter, it makes a new smart object that is not linked to the previous one, so updates to one will not affect the other.)
If I need multiple of the same smart object with at least one being a parametric filter, the workaround is to apply the parametric filter first and then base everything on that new smart object, which requires extra foresight and is not ideal.

It would also be nice to be able to have more than one parametric filter on a single layer (and to show a specific filter name instead of just "Parametric filter").

I think the Parametric Filters feature is the type of thing that many people won't realize its full potential at first, but when people start doing amazing things with it, it will slowly catch on, and it will become a major part of many workflows.
