I actually thought this was on another feature request but as I am unable to find it - will log here. It is closely related to the feature request for "Export List of Users & Data" which I would love to see happen on the same admin screen. Currently the list of users can only be sorted by Name, Email, or Last Active. In an enterprise with many users, this is too cumbersome and the ability to check basic membership of specific roles, especially custom roles would be ideal so that for example, members of a group "Team Leads" could be filtered and viewed in this page. Likewise, being able to filter a user name, email, or other features should be trivial to implement for a page that already has a tabular view with clear headers for the columns.
