The group view in the UI has an audit query view, to see when users get added and removed in the group. But if you are troubleshooting a specific user in multiple groups, it gets to be more work flipping through pages and jumping to multiple groups. With an audit view on the user page, one can see a summary of all the changes for the user much quicker.

 

Note sure if this is the same as GRP-365 which is still open.
