Role Viewer Suggestion

There should be a list of roles, with another list of people in those roles, viewable by the public. Of course, seperate roles viewability can be disabled by server admins. The current workaround would be to scroll down the members list looking for the roles. In big servers, this really wouldn't be possible. in servers where roles don't have colors, it would be tedious, especially if there was 100+ people in it
