Filter Forge as Smart Filters for Photoshop Smart Objects

Yes this would be a very good idea and would be really great, but the problem I see is that the way filter forge works is much different than any of the other filters available you have put, and it needs to be rendered by the FF plugin each time.

I do not say that it would be impossible to make, as I really do not know, but maybe it would be more difficult to make than with other filter plugins

I was mistaken above. Filterhub is able to make Filterforge behave like a smart filter. I just ran a test where I changed every setting in a Filterforge filter. I wrote down all the settings filter and then rendered the photo. Then over in the layer I was able to relaunch FilterForge and with all the sliders exactly as I had set them before. And I was able to do this dispite running a different filter right before trying to recover the test one.

Filterhub has become one of the most useful filter tools I have. I never run a filter without it. It makes things much easier because it can function as a palette. IOW, it can always be open. And it can stamp the later before rendering. Or copy it. Or not. All automatically. And it can make dumb filters work like smart filters. But I never use that feature, which is why I should have tested it more before my previous post.
