Can a column be added to the Search Users page for Groups? It would be nice to be able to see all our users and sort them by groups.

Since they may be in multiple groups, what would be nice is to have them repeated in the results for each group they are in, but have these repeated instances be a lighter color (grey maybe?) so it's obvious it's a duplicate.

You could add options to the sorting I guess (repeat for multiple groups, sort by primary group (add primary group function to groups), sort using only one group (defaulted to the sort type of ascending or descending)).
