----Let me first just say that I don't hardly know anything about Photoshop and the like, but I have not seen this kind of option in the version of Photoshop I have used. That said, I have no idea if this is already possible or not, and if not, exactly what way it would best work, it's just an idea that came to me.
----I was thinking it would be interesting to be able to loop a filter's effect back through itself, or "double" it. Ideally, this would be done simply by clicking a checkbox. It could also be done, per control/module, for instance a little checkbox by each control, that if you wanted the finished image run through just that module at that setting again, you'd just click that checkbox, or a combination of them.
----Not exactly groundbreaking, or necessarily useful for everyday stuff, but you never know what an idea like that could lead to, or maybe someone could expand on it, or simplify it for better use. Just an idea.
