Some of the secret Leopard features revealed

In new builds of Apples new OS 10.5 “Leopard”, it seems that some of the unannounced secret features have come to surface.
These features include:
- A Firewall that now has the ability to limit certain applications and services with a pop-up that also notifies you of external machines that are attempting to access your Mac. (Sorry Little Snitch)
- Using Spotlight you can perform calculations and search the dictionary
- Apple has included a new utility with Disk Utility, File Recovery allows the recovery of deleted files. The utility allows files to be searched for and then recovered.
