View what groups/roles/user a permission is assigned to

At the moment you have to click a group, go into the permission editor look up the attribute and see what is assigned for that group. It would be useful to be able to look at an attribute and see how has the permissions and to what level.

For example I had a situation where a particular role/group recently couldn't do something do due to a restriction, but it wasn't easy to work out who did have the permission and therefore was able to edit previously.
