How to tell whether Little Snitch is running or stopped?
After a few hours, how can I tell whether Little Snitch is running or stopped?


If you enable the »Show inactivity warning in menu bar« feature (right below the button in your screenshot) you will see a yellow triangle if Little Snitch is not running.


  How can I restart it when it's stopped?


If it is not running, the stop button will change to a start button. Press it to start Little Snitch for another 3 hours.
