 Hey

 The message that shows up when updating plugins or themes should not
 remove the visible site. Instead it should keep the old plugin/theme until
 it has finished updating and then smoothly change over to the new without
 disrupting the frontend of the site.

 On fatal error it should automatically revert to the old and just give a
 message in the backend that it could not update to the new plugin/theme
 because of whatever reason. Then a message saying let the author of the
 theme/plugin know about the error.
