Full Admin Audit Trail vs System Update Feed

It would be nice for the WF Admins to see the full update feed as an audit trail for troubleshooting purposes, however, the rest of the users only need to see a limited amount of transactions.

We would like to turn off more items in the standard update feed but would want to have access to a complete audit trail at certain times, perhaps in the set-up area.

ProofHQ has a nice activity feed.
