It would be a great help to either include Drupal's ACL roles in CiviCRM's list of groups, or make the advanced search capable of filering the results by Drupal ACL role.
— Use case from Dave Lange in support of this issue —
I'm finding that I'm starting to duplicate my Drupal ACL groups in
CiviCRM. For example I have a set of bloggers and a set of membership
coordinators, and volunteer coordinators. Each group has different
access to the site. Instead of trying to manage groups like this in
two places, it would be great if we could narrow it down to one, or
just have them synchronized.
