Wish Obfuscate objects/variables that are generated and used with the designer

I started using Release mode with obfuscation and I've see that the objects generated/used in the designer are not obfuscated.

Also I've seen that only the method names are obfuscated (except the ones that contain an "_") and the parameters that the method accepts aren't obfuscated also local variables inside the method aren't obfuscated.

Also custom types could be obfuscated.

So basically my wish is to extend the obfuscation.

(Local variables and parameters are not kept by the Java compiler)
