Matt Curry has posted a screencast about some of the updates that he's made to the CakePHP Debug Kit:

I’ve been doing some upgrades on the CakePHP DebugKit and wanted to share them with everyone. I figured doing a quick screencast would be faster then writing a post. Was I wrong. It took me like an hour to record this, even though the running time is just over two minutes.

Included in the updates is the ability to select a page from the History and get all of the statistics for that request (instead of just teh current page like it was before). You can grab this latest version from his page on github: http://github.com/mcurry/debug_kit/tree/master.
