There is no doubt that Drush is a magical tool in the Drupal community. Two very useful tools in the Drush "Swiss Army Knife" include drush sql-sync and drush core-rsync. These tools allow copying databases and files between Drupal instances.

If you need to have access to run Drush commands on a production server or via a Drush alias for a production server, policy.drush.inc can help prevent some devastating mistakes. Accidentally overwriting production databases and files can impact you and your clients negatively. The Github gist below shows how the built-in Drush policy functionality can prevent sql-sync and core-rsync from running against any Drupal instance that has a destination with prod in the name. This works for Drush aliases too.

Vim setups can be very personal since there are so many configuration options available. While stock Vim can do much, it doesn't take very long to figure out that you need a plugin manager to quickly access a world of new functionality. Vim plugins can provide integrations, commands, syntax highlighting, and more. Check out VimAwesome to get an idea of what can be accomplished with plugins.
