title: The second Snackbar below a toolbar
body: <p>I'm conscious that in more cases there should be only 1 snack bar, but in my app, the best UX will be when I will display undo bar on the bottom and in the same time all alerts will be displayed on the top.
  Snackbar from support library doesn't work like that. Do you know any library that will let me display alerts on the top and undo bar at the bottom?</p>
  
  <p>Cheers</p>
