Provides a theme-independent administration interface (aka. navigation, back-end). It's a helper for novice users coming from other CMS, a time-saver for site administrators, and useful for developers and site builders.
Administrative links are displayed in a CSS/JS-based menu at the top on all pages of your site. It not only contains regular menu items — tasks and actions are also included, enabling fast access to any administrative resource your Drupal site provides.
What makes it even better is that it comes with RTL support(perfect!). There's a problem though with its D7 release candidate: the RTL just doesn't work well. Just when I was just about to scan the CSS to fix it, I found out that someone has already done the job. The solution can be found in this submitted issue: "No dropdown menus in RTL language"; hejazee submitted the magical patch at comment #34 and it works perfectly!
This patch is based on the development release, so make sure you install the dev release before applying it. Enjoy =)
