adding contextual menu item seems like a work around. the item should not show up on all files. if this is done at a deeper level it could be done better. for example you don't need to be super user to open a system config file, so you should only be asked for them when you try to save it.
also this is not just for system admin tasks. a parent might need to look through a childs home folder for example. -- Nautilus should have a superuser mode https://launchpad.net/bugs/12154 -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
