one effect many layers
I guess Im requesting a "Node" layer, in which you can place one or a group of effects. Then, similar to the new track matte layer selector, select a Node layer to apply the contained effects. Theoretically you could have a slider that "fades/blends" the Node layer effects with the original. And you could apply multiple Node layer effects to a single layer and change the stacking order of the nodes.
Unlike an adjustment layer, you can choose which layers will have the effects regardless of heirarchy.
You wont have to copy and paste effects to multiple layers.
Using the transform effect it might simplify the need for expressions where parenting doesn't work.
