Version: (using KDE 4.1.2) OS: Linux Installed from: Ubuntu Packages When attempting an action that is prevented by lack of permissions -- for example, trying to edit a config file under /etc or /boot -- instead of merely getting a permssions error, the user could be presented with a dialog informing them that there was a permission problem, and asking if they want to retry the action with kdesudo/kdesu. Naturally, this would be accompanied by the necessary warnings; also, it should be only activated if the user is in the sudoers file or has execute privileges on /bin/su, as appropriate.
