I love the computer and user OU overview option, however as it is displayed currently it doesn't make any sense to me, or anyone with many OUs and sub-OUs. The proper way to display an OU structure would be in the tree view that AD is naturally organized by, displaying all container levels.
A simple example - each item is an OU, though not all necessarily contain computers/users, they may be simply organizers for sub-OUs:
Workstations (110)
----- Department 1 (60)
---------- Title 1 (20)
---------- Title 2 (20)
--------------- Sub-title 1 (15)
--------------- Sub-title 2 (5)
---------- Title 3 (20)
----- Department 2 (50)
Servers (30)
----- Virtual (10)
---------- Citrix (5)
---------- VMware (5)
----- Physical (10)
Forgive all the dashes, I couldn't leave empty spaces. Please let me know if that needs further clarification!
