Drupal developer's tools

Smashing Magazine is one of my favorite sites when it comes to design. The site is always insightful, and has an abundance of tips, links and ideas that you can be inspired by.

A few days ago they published a Drupal Developer's Toolbox. It has a lot of tips, tools and ideas, from novice and basic to the expert and customized.

I think that any drupal developer can find useful information and ideas in the article itself and the links attached to it.
