I think what he is asking, and I also think this would be a handy tool in route/session development, would be something like:-
- Right Mouse Click on a layer in the Layers Palette (currently this opens a menu with "Delete", "Rename", "Merge Up" options - with "Edit" instead of "Merge Up" for Effect layers)
- Select a new option (probably only for non-effect layers) "List Assigned Assets" (or similar)
This option would produce a list of assets (Name, KUID, Type) of all the assets assigned to that layer.
My suggestion anyway.
