Would like to request that Immunity Debugger be added as a replacement to or an addition along side of OllyDBG.

From the Immunity website:

Immunity Debugger is a powerful new way to write exploits, analyze malware, and reverse engineer binary files. It builds on a solid user interface with function graphing, the industry's first heap analysis tool built specifically for heap creation, and a large and well supported Python API for easy extensibility.

A debugger with functionality designed specifically for the security industry
Cuts exploit development time by 50%
Simple, understandable interfaces
Robust and powerful scripting language for automating intelligent debugging
Lightweight and fast debugging to prevent corruption during complex analysis
Connectivity to fuzzers and exploit development tools

Oh yeah, OllyDBG is up to V2.00 and supposedly v2.02 is around the corner.
