So I've been using the Admin Module for Drupal recently to create a better backend for my clients, who end up using the site to create and edit content extensively, but did not have to piece all the nuts and bolts together. This module creates a nice page for getting to the all of what my clients usually need, and frankly, most of what I need. AJAX is just the right places, this module delivers a smooth, enjoyable administrating experience. Although, I don't think I could ever handle not having the Admin Menu module installed too.
