Leopard to Include a Data Recovering Tool

One can always delete a file by mistake, and it is often a pain to recover them if no backups have been made.
According to one of the screen captures of Leopard published on aeroxp.org forum, Apple might introduce with Leopard a data recovering tool.

This data recovering feature will be integrated in Disk Utility. Of course with such system, chance to recover deleted data are the best when data have been recently erased, files and HD not too much fragmented, etc.
Maybe Apple will also provide an integrated defragmenting tool in Leopard?
