(1) Review Option: We would like to provide a way to flag portfolios that have been "reviewed" by an instructor. This would be similar to the "hide/unhide" option for portfolios, but would only be available to users with a new "osp.presentation.review" permission. The review status would be saved in the currently unused Portfolio.isDefault flag (thus requiring no database changes).
(2) Review All Option: We would like to provide a way for authorized users to review "all" portfolios, regardless of whether the portfolio has been shard with them. This would aid instructors review portfolios even if a student forgot to share it with them. The view-all feature would be restricted to users with a new "osp.presentation.review" permission and would only be enabled if the following property was set in sakai.properties: osp.presentation.viewall = true (default is false)
