Dummy Layer with particular dynamic

Sorry but i don't understand if this possible new feature (adjustment layer) is interesting or not?
I would try to do an implementation, but if is useless or not interesting i will do other.
What do you think?

Hello,
i think that would be very useful a dummy layer that can contains a particular
effect/operation like curves in order to change parameters in future without
any problems and eventually using a particular mask for handle particular zone
where i don't want this.
In this case is possible to activate or deactivate effects and change that
parameters dynamically without any duplicate image layers with static effects.
The problem may be in a user-defined plugins but for standard operation like levels or
curves there isn't or i'm missing somethings?
If i write an effect plugin would be perfect to associate that with this kind of dummy layer in order to change parameters/enable/disable/masking/unmasking that whenever i want.
Sorry for my english :),i'm not a mother language...

Jack

Well, adjustment layers is what GIMP developers seem to refer to as
"layer abuse" :)

There are different ways to implement non-destructive editing. Would
you be interested to find out more?

I would be very interested in a non-destructive way of applying a curve
to an image. A method that would allow later modification of the curve
without having to rebuild everything that had been worked on since. Is
there a proposed mechanism to support this?
