Wouldn't it be great if we had something similar to the "log" inside the Adobe Analytics Admin console, just with an overview of where the different evars, events and props where used, for any custom report that is built inside report builder, data warehouse requests, Workspace and which calculated metrics etc.
It could be either a search functionality or a request that could be downloaded with a specific timeframe, just like in data warehouse.
This would make it easier for people to see if the data is used or if it's just sitting there for no obvious reason (especially when going through implementation).
