This plugin adds an additional tab to the project dashboard showing the project roles and current assignments for this project. This is useful, if you use project roles in your permission schemes or workflows. This tabs give the project members the possibilty to look, who has which role in the project. (This is normally only possible for the project admin in the administration section of the project.)
Since v2.0.0 only project roles are shown, which have Browse Projects permission in the permission scheme assigned to the project. Also only users with Browse Users permission from global permissions get access to the tab to show the project role assignments.
