I believe the ability to set favorite system actions would be desirable. While the current order (logout,lock-screen,reboot,shutdown) is desirable for some, others might want less options visible, more options visible, or specific options instead of default, for instance, in my case, I prefer having logout, suspend, shutdown. Kickoff shows all system actions; Kicker and Application Dashboard show only three but have a section just for system actions, which in turn can also be set as favorites. Simple Menu displaying only a specific subset of system actions (4 out of 6) is unlike the other menus (in particular since Kicker and Application Dashboard consistently display three and not four) and doesn't seem to provide as many choices to the user.
