It bugs me that the Admin screen is in one column. There is plenty of room for two, so anyone who wants two columns should edit their theme css file in themes/amity_island/css/admin.css, and look for the css:

div.admin .left, div.admin .right {
  margin-left: 0em;
  margin-right: 0em;
}

and change it to:

div.admin .right {
  float:right;
  width:48%;
  margin-left: 0em;
  margin-right: 0em;
}

div.admin .left  
  float:left;
  width:48%;
  margin-left: 0em;
  margin-right: 0em;
}
