Developing .NET obfuscator (freeware). Looking for feedback.

Question

I'm developing a .NET obfuscator (freeware)

Features (as of version 0.7)

    * Obfuscation of names of the types, methods, fields (including public names and virtual methods, when possible)
    * Wiping out namespaces, property and event definitions (when possible)
    * Fine-grained settings system
    * Generation of the map of the obfuscated names (decoding of stack traces is currently under development)
    * Encryption of constants

Command-line interface only, at the moment.

Feedback is welcome - what you like or don't like in the application, what features you'd like to be implemented, etc.
