Better Formats

The best part about this module is that each role can have a default text format.

Drupal 7 core allows for reordering the formats in the UI, thus picking a default too. However, there is no role based ordering, as there is with the Better Formats module.

Devel

Essential module for developers. Should be disabled in production environments.

Search Krumo

Use search Krumo Search to extend Devel to get a search box for your dpm(). A new search box appears above all krumo prints.

If you use sdpm(), you get a really nice feature that lets you copy the full path of the variable, "for the lazy programmers"...
