Log Audit Log Searches and Exports in Audit Log
Every global Admin can access the audit log - there is no way to control the usage of the Audit log !
Audit Log can contain sensible user data and every global Admin can access this information without any documentation.
So please log every search in Audit Log - who has searched what.

This is a pretty important request for countries like Germany where privacy laws are a bit more strict than in other countries. The current behaviour (where noone could track searches of admins in the audit log) could cause some trouble with workers councils which protect the privacy of employees.
