Right now, I know it's possible to test someone's permissions and to check someone's permissions on a particular node as per "Analyze Permissions". I am suggesting an "Analyze Node" and show you which groups/users have the permissions on that node. For example: A general just Analyze Node and a breakdown of the groups that have permissions there and which ones, perhaps minimized by default, so one can see at quick glance the general data and then expand if necessary. Or the ability to also set specific criteria. Like Analyze Node for "Post New Threads" which will show you users/groups that have that specific permission(s) that you set.
