When the user clicks on the arrow to move an user, the arrow changes to a spinning signifier to indicate that the the process has started.
After clicking on the arrow an overlay div goes over the whole UI to avoid fast clicking
Moved success/error messages to be dismissible alert messages
Changed the location of success/error messages within the list instead of above them
