It would be super cool to be able to not only see but also edit the groups a user is in when I have the user property page open in the Web gui.
At the moment I see which groups the guy belongs to but nothing else.
How about having a small table with all the available groups and a simple click box in each row to add/delete the user to/from a group.
Similar to the lower part of the group-edit page just the other way around…
Just an idea …
