Whoa the Devel Module!

So I joined the Drupal-dojo group and I'm trying to keep up, but they move fast! I started watching the lesson #1 video (screencast):


I finally installed the Devel module and all I can say is this is soooo coool! Never have I seen a framework provide such a tool for the developers to use.

If you are a developer like me, you may have your web server set up to show all errors. Well this does not work so well with Devel since it starts to show tons of Notice errors. I changed the error reporting in index.php:

error_reporting(E_ALL & ~E_NOTICE);

but I wonder if there is another way to set the error reporting?
