Smashing Magazine has put together a new post that provides a "Drupal Developers Toolbox" with links to resources all over the web.
After publishing the recent WordPress Developer's Toolbox, there were several Drupal developers calling out for equal coverage. In this post you will find a thorough collection of all kinds of resources that will aid designers and developers working with Drupal-powered websites. This collection is intended to simplify your tasks and save you time when working with Drupal.
They've broken it out into some of the basic components you might need, modules, a few sites offering some design inspiration, themes, tutorials and more.
