Does anyone use Drush? It's a command line interface for Drupal and personally I find it a big time saver, it saves me a lot of time that would otherwise be spent clicking through menus to carry out tedious tasks. It makes module installation and enabling extremely simple. It can also save you a lot of fixing if you manage to mess up your theme to the point where you need to change the default theme to something else.
